Between monthly dosage

Using a product that was not effective to kill fleas. Could not change to a month long flea prevention medicine. Placed these in a spoon off tuna. Cats loved it. Glad on cats started to die about 30 minutes later. Continuing until they can go back to a monthly preventative.

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.

Works Quick

This stuff works great. As advertised, within maybe 5 mins of giving this to my cats the fleas were dying and falling off of them. They both got hyper for about 30 min, running and scratching all over the house but then they calmed down and were able to sleep in peace without fleas biting them.
