Does anyone here have the vet give their cats a shot for the fleas? I was just wondering how good it works. I was thinking about trying it on Stinkie. He is allergic to fleas. He has feline miliary dermatitis and the fleas cause him to itch really bad and causes sores. His skin gets hot and he washes a lot more often than a normal, healthy cat would and all of the scratching and washing is causing him to lose fur. And it always gets bad in the summer and not much of a problem in the winter. I guess it's because the fleas are worse in summer. The hotter the weather is, the worse he gets. I just want to help him somehow. Does the shot work better than the frontline and is it cheaper or more expensive? Any information or experiences anyone?
