Giving a cat a pill can be a nightmare.
The easiest way to give a cat pill is to crush the power into a powdery form by putting it between two spoons.
If the medicine happens to be in capsule form, all you have to do is pry the capsule apart then sprinkle the medicine on some wet food and serve it to your pet.
When you get your gun, your vet should show you how to use it.
If you aren’t comfortable using the gun, you can always try giving your cat his pills by hand. To do it this way, you’ll need to hold your cat still, and open his mouth with your hand.
If you can’t get any of the above techniques to work, you can always go to a local pharmacy and get them to a make flavored gel or liquid using your cats medication.
