Thanks for using Petco Pet Education Center, formerly Petcoach! Not typically. Usually fluid filled bumps or hives are seen with allergic reactions more than with flea allergy dermatitis. With flea allergy dermatitis, usually cats develop ulcerated lesions that tend to be very itchy. Good luck and have a good night!

I have a 13 month old Bengal Tom. He has developed clusters of small hard bumps/lumps on his undreside and top neck/shoulders. These are small 1mm bumps in clusters of 6/10 in 3 sites. I originally thought them to be fur knots in his fine fur which i
Thanks for using Boop by Petco! This is likely a skin infection which may be secondary to something like allergies. The infectious component would have to be taken care of but it is crucial to take care of the possible allergy as well so this does not continue to happen. It really comes down to figuring out what is causing his allergies so that they can be treated or the specific allergen avoided. There are many things that can cause allergies though in most cases they can be broken down into 3 big categories: flea, food and environmental allergies. Allergies are usually worked up in a stepwise fashion starting with flea allergies as this is the easiest and cheapest to take care of. If not on a flea preventative, then it would be a good idea to get started on one. If already on one then it would be a good idea to change to something else (there are many new products out in the market). If not improved in 1-3 months then it is time to move on and check for food allergies by switch

Thanks for using Boop by Petco! Fleas can actually still affect indoor cats. Other types of allergies should be considered.

My cat has hard bumps on his chest and arms and one on his tail. They look a little yellow but are also scabby. Do you know? Could he be allergic to fleas?
It is possible this is a condition called miliary dermatitis, which can be a reaction to flea allergies, among other things (can also include other insect bites, airborne allergens, food allergies, fungal infection and more). A vet exam is recommended to help determine the cause and some of these kitties do need antibiotics for secondary bacterial infection and steroids to stop the inflammatory cycle.

This is probably caused by an allergic reaction. first of all make sure you de-flea Sybok 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.

My cat has these pimple like bumps around her neck and on her hind legs and a little bit on her tummy what is that from and what can I use to get rid of it what could be causing it
It sounds m as if your cat has a skin infection, most commonly caused by an allergy or fleas. The allergy could be a due to a protein in Daisy's food or an environmental allergy like to dust, pollens, grasses, etc. The allergy causes your cat to itch and chew at the skin which breaks down the skin barrier. This then leads to infection (the bumps you are noticing). Daisy will need antibiotics to help clear up the infection and possibly an anti-itch medication like steroids or Atopica to give some relief while the infection clears up. A medicated shampoo may be beneficial as well. I would also recommend she be on a good flea control too. I hope this helps. Thanks for using Boop by Petco Best of luck!
