If your cat has had fleas, there’s a chance they have tapeworms too. Tapeworm segments look similar to grains of white rice and are visible when stuck in your cat’s hair under the tail or by the back legs or in their poop. It’s not always obvious that your cat has tapeworms, so the best way to identify a problem is through an exam performed by a veterinarian. Use Bayer Tapeworm Dewormer for Cats to treat your pet.
