Just because your cat doesn’t venture outdoors doesn’t mean outdoor parasites can’t get inside. Mosquitoes transmit heartworm disease, and as you probably know, there is no such thing as an “outdoor only” mosquito! Plus, fleas and ticks can both hitch a ride on clothing, so every time you come back into the house, you could potentially be bringing these parasites in with you. If you have only indoor cats, you may be able to get by without preventatives, but call us – we’re happy to discuss this with you.
