My cat has a swollen paw. She's running around on it fine, she just keeps licking it. Could it be an allergy?
It sounds like your cat came into contact with something that irritated her paw. It could be an allergic reaction or it could be that something is stuck in her paw/between her nails, especially if she has been outside.
If you are able to, check to see if she might have an ingrown nail or for any signs or redness/painful areas. An ingrown nail can be very painful and you may need to take her to the vet so it can be properly treated. If she is licking her paw, she might be itchy or she might be trying to soothe her pain. If a particular area is tender, you’ll be able to tell by how she reacts when you touch it.
If she is not in pain and you can’t see any sign of injury, you might want to try soaking her paw in warm water with something very gentle such as Epsom salts if you keep that on hand (you may find something at a pet shop for this purpose), but be sure to dry the paw carefully after. If it seems to provide her relief, do it a couple times a day. Your cat may not love the bathtub or the laundry sink, so you may want to soak her paw in something small like a foot bath or a small pail.
