How To Get The Cat To Take A Cat Flea Tablet?

Some cats, will eat a pill that has been crushed and added to their food. Mostly however, cats don’t tolerate this sort of behavior from us and will leave the food untouched.

It can be frustrating as we know we are doing what is best for kitty but kitty has other ideas and being obedient isn’t one of them. Fortunately there are other ways of giving the cat a tablet.

  1. Using a pill popper or pill shooter is a popular and convenient way to give a cat a tablet.  It may take some getting used to however it is worth persisting. Life will become easier when ever kitty needs to take a pill. There is detailed information here about how to use a pill popper.

  2. Another excellent option is to use a gel capsule. The capsules are purchased empty and the pill is then be added to the capsule, whole or crushed. Approximately 200 capsules are in the bottle.  This is in preference to purchasing 1000 gel caps (way too many) in a plastic bag.
