My cat has a pussy, pink bump on its chin. Could it be from fleas?

This looks like it could be a scab or potentially feline acne. Feline acne can be related to using a plastic or dirty food bowl so you may want to switch to glass or ceramic if you have a plastic bowl. It does not typically require treatment and does not bother the cat. If this lesion is getting bigger, if you notice redness or discharge or if it seems to be bothering Lydia I would recommend having your vet examine it.

This could be a pustule which is a local bacterial infection or even a small cyst. If it is just one it may go away on its own. But if there are multiple, this one becomes larger or seems painful your cat may need medication from your veterinarian.

This could be a bug bite or a small growth. If it is not painful and not getting bigger then I would watch it and have her seen by your vet if it doesn’t go away in a few days. Sometimes I need to poke a growth with a needle and look at it under the microscope to determine the cause. This is not necessarily an emergency but should be seen and worked up if it doesn’t go away in a few days or gets bigger. Watch for discharge from swelling, change in appetite or energy level.

This looks like a small, localized spot of infection, sometimes referred to as a hot spot. If the infection is contained to this one area you can try to treat it at home with some topical antibiotic ointment (like Neosporin). If this does not take care of the problem, or if there are other areas like this on her skin, I would recommend having her checked out by your vet so a systemic antibiotic can be given.

This looks like a mild skin infection. I suggest you use these medicated wipes on the affected area once a day. If no improvement in 7-10 days then Pepper should be examined by your vet. ( https://www.allivet.com/p-5393-douxo-chlorhexidine-3-ps-pads-for-dogs-and-cats-30.aspx )

This is probably caused by an allergic reaction. first of all make sure you de-flea Pixie regularly every month with a high quality spot on (ex. Advantage) as fleas are by far the most common reason for these reactions. If the fleas are not the problem, it could be an allergic reaction to food or an environmental factor. this is more complicated to treat and will sometimes require medications such as Steroids, anti histamines or cyclosporin in order to stop the allergy.

Given the location of the white bumps on Kira's chin, it's most likely that this is a case of chin acne. Cats tend to develop this condition as a result of eating/drinking out of porous bowls, such as plastic or ceramic. While I don't know which type of bowls you're currently using, I would recommend using either stainless steel or glass bowls, taking care to wash them daily. This change should help minimize the chance of future recurrence. For now, you can clean Kira's chin with an antiseptic cleanser, like chlorhexidine (Hibiclens is one brand) twice per day. Be sure to rinse his chin after wiping with the cleanser! If the bumps persist in another week or two, or if they get worse at any point, then you'll need to take Kira to his vet for further evaluation. I hope that everything goes well!
