Doesn’t work
Purchased these pills about a month ago and my cats still have fleas. All four of my cats took them and the house was cleaned and vacuumed and my cats still have fleas. Very disappointed.

The best!
I bought this 3 1/2 months ago. I haven’t had a flea infestation since 1990, much has changed. This product is the best! I have my cats on a monthly topical flea treatment. I spotted my outdoor cat, Rudy, laying next to a strange cat and the next thing I knew it was flea explosion! Those fleas overwhelmed my poor Rudy. I tried several methods from the past and then found these pills! Thank God, they worked.
