Fleas have evolved over time to have many specializations which make them successful at targeting cats specifically as hosts.
But when those cat fleas cannot locate their desired host in their environment, they will be opportunistic and feed on virtually any animal or person that can provide them with a blood meal.
For this reason, if you have a cat that is infested with fleas and you also have dogs in your home, the dogs can be bitten by cat fleas.
Give your pets a suitable flea medication which will kill all species of flea and protect them from flea bites which can spread disease and misery.
