Why do I swell when my dog scratches me

Have You Ever Wondered Why A Cat Scratch Itches and Swells?

If you own a cat, you know that scratches can happen when you least expect it. They might be accidents, such as when your cats rear claws scratch your legs when it leaps off of your lap, or they could be intentional, often a product of your cat feeling stressed and needing to protect itself by clawing.

Most cat scratches are extremely superficial, meaning they only affect the topmost layer of skin. Even then, you might find that a cat scratch swells and leaves you feeling itchy until the skin heals. So why exactly does it do this, and is it indicative thats something is wrong?

Some swelling and itching could just be part of your bodys natural response to skin damage. A typical scratch will result in minor swelling and itching as the immune system fights off potential infection and your body works to heal the wound. If it is deep enough, the scratch may also cause a scab to form, which causes minor itching in some people.

However, another condition might be causing your little cat scratch to drive you mad with itching and discomfort. Cat Scratch Disease, or CSD, is a common bacterial infection that can be transmitted through even the smallest scratches from your feline friend.

Understanding Cat Scratch Disease

CSD can occur if your cat bites or scratches you or licks an open wound on your body. The disease is caused by a bacterium called Bartonella henselae, which gets into your cats bloodstream through flea bites and flea dirt. It is most commonly found in a cats saliva and is usually transferred to the paws through grooming.

Your cat might be a carrier for the bacteria, even if it doesnt appear to be sick. Cats are usually not affected by the bacteria and will remain healthy. The best way to prevent your cat from carrying the bacteria is to bolster its immune system and watch out for flea infestations.

Kittens are more likely to carry the bacteria and are also more likely to bite or scratch people due to rough play techniques, resulting in higher rates of infections in households with kittens.

When a person is infected with bacteria from a carrier cat, a simple cat scratch can turn into something much more frustrating. CSD can cause small bumps or lesions with pus on the scratch location, as well as a fever, exhaustion, swollen lymph nodes and headaches.

Symptoms of the infection may not appear until up to two weeks after the initial scratch occurs, so you should pay close attention to the scratch and keep it clean. Watch for symptoms like swelling and itchiness during this time to ensure you havent been infected.

Fortunately, if you do get infected, CSD usually stays relatively minor and will clear up on its own. If symptoms dont clear up after a month, you should see a doctor.

Treating and preventing CSD symptoms

If you get scratched by a cat, the first thing you should do is thoroughly wash the area with soap and water. This may help prevent the bacteria from getting into your skin. Then, apply an antibiotic ointment to the scratch, followed by a band-aid or gauze pad. Taking an over-the-counter pain reliever or antibiotic may help relieve your symptoms.

The best way to avoid CSD is by preventing scratches in the first place. You dont want your cat to be scratching people, anyway, because of the potential health risks and because your cat may develop bad scratching habits over time.

Be sure to trim your cats nails regularly so it doesnt have long claws to lash out with. This will also help prevent accidental scratches while playing. Additionally, avoid playing rough with cats and kittens. Rough play often encourages biting and scratching in young cats, in particular, that can transfer over to their adult lives.

If you have an open wound, do not let your cat lick or touch it to prevent the spread of any kind of bacteria.

Close attention to symptoms can help determine the severity of a scratch

Sometimes, deep cat scratches will produce swelling and itching sensations, but will not be infected by the Bartonella henselae bacteria. To determine whether you have CSD or not, make sure to monitor your symptoms for two weeks after the scratch and pay attention to how your scratch is healing.

If you do get diagnosed with CSD, check over your cat to make sure it is still healthy and happy and unaffected by this irritating bacterial infection after treating your symptoms.

Why Do Cat Scratches Itch and Swell?

If youve ever had a kitten, you may have asked yourself the following question, Why do cat scratches itch and swell? or even Why do cat scratches sting? There are two possible answers to that question.

The itching and swelling that comes quickly after a scratch is part of your own bodys reaction to any damage done to your skin. But it could be a bit more

It Could be Nothing

Most scratches are superficial. Even if you end up with itchy skin (and a bit of frustration), there is nothing more to it.

Simply put, they are thin lines of broken skin, much like a paper cut but less regular.

It may not be significant enough to cause your body to produce endorphins to suppress the pain and thus they sting more than it seems they should for how small they are.

Or a Nasty Bacterial Infection

However, if after a few days the symptoms persist and your itchy skin turns into something more serious, you could have caught cat scratch disease / cat scratch fever

Additional potential symptoms :

• Localized Lesion (appears within 3 to 10 days)
• Localized swollen lymph node (after 15 days)
• Pus
• Fever
• Headache
• Poor appetite
• Exhaustion
• Disseminated disease

Even though cats spend much of the day bathing, they can still be carrying around some nasty bacteria.

The Bartonella henselae bacteria in particular is the one causing that infection. This gram negative bacteria causes the cat scratch disease otherwise known as Bartonellosis.

About 40 percent of cats have it at one point or another in their lives so it is fairly common.

They can very easily share it with other cats and with their people. Kittens, who seem to do the lions share of scratching and biting at play, are most likely to have (and share) this infection.

Where Does the Infection Originate?

Cats are reservoirs for this bacteria but there is an additional culprit.

Fleas. Yes, here once more to ruin the day.

Fleas are the main vector of transmission for this bacteria. This means that a cat can easily transmit CSD to other cats through fleas.

The bacteria live under the cats claws where flea droppings collect when kitty scratches.

As she cleans her paws, she ingests it. The infectious disease travels through the bloodstream and eventually into your cats saliva where it comes into contact with you. However cute as it seems when kitty licks your skin, you might be asking for trouble if you allow her to continue!

Bear with us here as we get more technical. If the bacteria gets through your skin, it will invade the endothelial cells and lead to acute inflammatory reaction and lead to a pro-inflammatory cascade.

It does not sound very good but rest assured that most infections can be treated quite easily.

But My Cat Isnt Sick! Full Diagnosis

These bacteria can be present in cats or kittens even when they appear to be otherwise healthy. You will most likely be the one to develop the symptoms.

Once you start suspecting cat scratch disease, the best way to find out is to go to your doctor and get tested.

He/she will perform a serology test or a PCR and in more serious cases a Lymph node biopsy (that last one is pretty rare).

This will tell you for sure if thats what you got.

How to Treat Cat Scratches or Bites

Cat Scratch Treatment & First Aid

If youve been badly bitten or scratched by your cat, wash the wound carefully with soap and water.

Treat your injury with an over-the-counter topical antiseptic and cover it with a sterile dressing until the wound heals.

As you probably understood by now, if you develop other symptoms within two weeks of the scratch, that could mean trouble. If this happens or if you develop a fever, or see swelling in lymph nodes, seek medical help.

Cat scratch disease treatment

Often time this is a self-limiting disease which means that while closely monitored, it will be left to heal on its own.

But if the symptoms are a bit too strong, your doctor may prescribe Azythromicin for 10 days to 2 weeks. He may even combine it with Rifampin if the disease appears disseminated.

How To Prevent Cat Scratches And Cat Scratches Disease

There are several things you can do to prevent your cat from scratching you.

Adapt your behavior

If your cat likes to play it rough, you need to channel that energy into something first, before actually playing with him/her. You need to anticipate his/her moves better and deescalate the fight if it becomes too rough.

Be the smartest animal and try to keep your play session in control so you dont get unnecessarily scratched.

Cats nails are sharp : trim them

First, wed highly recommend getting him one scratching post in order for him/her to get his full energy on something made for this purpose. It will also naturally render his nails blunt.

Secondly, if you can, we recommend that you trim your cats nails often (every two weeks if you can). It takes a bit of practice but it really helps make their nails less sharp, reducing the risk of penetrating your skin too deep.

Less unsupervised outdoor time

Then, if you cannot supervise your cat when he is outside, another option would be to keep your cat indoors or prevent him/her from hanging out with potentially contaminated cats (although that may not be that easy).

Flea prevention

Finally and this may be the most important advice to protect your cat and prevent CSD, if your cat often goes outside anyways.

Make sure your cat is protected by a flea prevention medicine (weather its a collar of a spray, this will keep fleas at bay, reduce the risk of carrying the disease, avoid a flea allergy and prevent a flea infestation)

How to Get Rid of Cat Scratch Scars?

Even after proper treatment, you may still end up with a little scar. There is no magic formula to completely get rid of it because it depends on your skins ability to heal. Some people heal faster than others, nature isnt fair!

However, we have found that using natural vegetable oil helps in that process. We highly recommend castor oil for that matter ! This oil is amazing and helps with the production of collagen and elastin. Do check this secret remedy!

Final Thoughts: Why Do Cat Scratches Itch and Swell?

If your skin is punctured or torn by your kittys claws it might itch or swell.

Dont be alarmed as it is a normal skin reaction. But, if you develop other symptoms following such an injury, you might have CSD. Seek medical help.

The best answer for your fur baby is to keep fleas away from your cat. Therefore, a really good flea protection program is essential.

Additionally, keeping your cat inside and away from other cats that might not have such caring parents is also a good plan.

Ultimately, the surest answer to cat scratch issues is to practice good first aid when kitty gets rambunctious.

Since it is kittens who are most likely to have the Bartonella henselae infection, they present the biggest risk to humans. Unfortunately, these frisky fluff-balls with their needle claws and sharp little teeth can spread the disease to their people as they play. Stay safe !
