I have a male cat, Speedy, about 4 1/2 years old. He deveoped a flea
bite allergy about 1 1/2 years ago. The sratching and overgrooming left
bald areas on his legs and under his tail.

Vet gave Speedy an injection of a steroid for the itching and said to
put Frontline Plus on every month. Worked fine and all bare areas filled
in like new.

A few months later small bald areas began showing up again even though I
had been using Frontline every month.

A second vet said the same as the first, with the same recommendations.
Speedy got another shot, and some pills for a couple weeks. The hair
grew back again.

A few weeks ago the bald areas began showing up again. I do not like the
idea of getting Speedy another steroid injection. I did get some of the
pills, Triam.

Now to the point. Are any of the less expensive flea killers as
effective as Frontline? Does anyone use the products available in
department stores? There are several that come in small vials similar to
Frontline for only about $8 for 3 doses. I think Hartz Mountain has one
of these products.

What's the differece between these types of flea killers and those like
Frontline that cost $39 for 3 doses?
