In Florida, all dogs and cats are susceptible to getting intestinal parasites and heartworms. Even though your cat may ‘never go outside’, a single mosquito can get into your home and bite your cat and give him/her heartworms. Also, fleas are great hitchhikers! One flea brought in on your pant leg can bring havoc for quite some time, laying thousands of flea eggs that will hatch later. Revolution is a very safe, effective, inexpensive and easy to use product that can protect your cat from these dangerous ‘bugs’.
