We have a little grey persian who is the best cat, (of some pretty good cats) that I have ever lived with. I comb her several times a day when she jumps in my lap at the computer. I use a comb with wire metal teeth, close set, that combs out dirt, hair and even fleas. In the height of the flea season I can kill ten a day off her head and neck. It's very satisfying and keeps them from ever getting a foothold.
The local numerous squirrel population is the source. She's an inside-outside cat.
By the first of the year I usually have the fleas totally wiped out, and as none are breeding outside, she gets a few months of flea-free life. The last flea came off in late February.
I keep combing through the non-flea months. She likes it and it cuts down on the shed hair. I've combed off enough fur to stuff a sofa off this little eight pound cat.
Yesterday I killed the first flea of the year with the comb. It's the Spring Fleaquinox!
I don't know what you do to celebrate the Fleaquinox. Just hunting and killing fleas is fun enough.
Update: So far just the one.
