Worked great on the cat.

Gave the 14 pound cat his pill in the afternoon and it seemed to work immediately. He took a long nap and didn't seem to bother him at all. Worked better than the flea collar or drops did.

These tablets work!

My barn cat used to have a lot of fleas, even when using a monthly drop treatment. After the second week, the fleas would start coming back. I started giving her one of these tablets, crushed up in her food, once a week and almost all the fleas are gone! I still use the drops, but now they work all month.
