Maybe, but it’s unlikely. There are 87 causes of itching in the cat and in the Edmonton area fleas would be near the bottom of my list. The most common cause of itching that I diagnose in outdoor cats is otodectic mange – commonly referred to as ear mites. Along with the scratching you may also notice shaking of the head and if you massage the opening of the ear canals you can usually send a cat with otodectic mange into a fit of scratching.
Scratching is certainly not an emergency; however, if you think that your pet has fleas you should have it examined by Delton Veterinary Hospital as soon as possible because dealing with a flea infestation is much easier if identified early. Plus, fleas are indiscriminate eaters and will bite you too.
