A cat that is infected with coccidia cannot pass the infection to dogs and vice versa. Coccidial infections in cats occur only by swallowing the coccidia in soil or cat feces or by eating intermediate hosts.
What diseases can be passed from cat to dog?
Parasites such as roundworm, tapeworm, hookworm, or whipworm can sometimes pass from cat to dog through fleas that are infected. Dogs are notorious for taking snacks from the cat's litter box if it's readily available.
How long does it take for coccidia to show up in dogs?
They lie in the environment and eventually sporulate (mature) into a more developed oocyst which can infect the dog again. Other dogs, cats, or mice may also become infected. This process can occur in as little as 6 hours, but it usually takes 7-10 days.
Is coccidia contagious to other animals?
Coccidia is contagious between dogs. Fortunately, the protozoa are host-specific, so while cats can become infected with certain subspecies of Isospora, your dog cannot pass the disease to cats in the household. Similarly, the disease is not contagious for humans.
How contagious is coccidia in cats?
Remember, the most common form of coccidia in cats, Isospora felis, is not contagious to people or dogs, and most adult cats eliminate the infection without any treatment.
