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.
