A Must Have for Fur Parents

Pet Armor Cap Action oral flea treatment for cats is a stable in my home. I have multiple cats, who venture outside. I crush the tablets and put inside a “delectable” treat. The capsules kills fleas 30 minutes later. Wonderful!

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.
