ask your cats doctor and see what they say.
I would not recommend it. I do know you should never put the canine Frontline on a cat. You should use the canine Frontline for the dog according to his weight and the same for a cat, use feline Frontline only. Why mix them?
Once your cat is 8 weeks old, you can begin using Frontline Plus. There is no weight requirement.
No. Frontline products should be used on the specified species. This is because one of the main components of Frontline, S-Methoprene is needed in a higher dose in cats. This is because it does not last as long in a cat than in a dog. So, if you used Frontline for dogs on your cat, it may not be as effective. However, this higher dose is still safe to use on a dog - so you could use Frontline for cats on a dog.
There is no information about not using Frontline on cats with any medical disorders. However, there are some drug interactions with Frontline, so if your cat is on any medications, it would be wise to consult with your vet before using the product.
According to the documents on the Frontline website, Frontline Spot-On treatment is deemed safe to use on pregnant cats and kittens above 8 weeks old. If you are unsure, contact your vet.
Don't do it, not suitable for cross species use. Buy appropriate flea treatment for the cat, it will be much cheaper than the vets bills.
Best wait until it recovers from the cold because Frontline is a chemical and some cats have a bad reaction to it, even when they are healthy. A cold means the cat's immune system is overloaded fighting off germs in the cat's body.
If you have multiple cats, you should treat them all with Frontline Plus application at the same time. You may want to keep the separate right after the application to cut the risk of them licking the medication off each other.
Frontline by itself should be sufficient to deal with your cat or dog's flea problem. Using a flea bath will reduce the effectiveness of the Frontline (you should only wash your dog with a gentle shampoo to maintain Frontline's protection).
Frontline for Dogs is not dangerous to cats (or Frontline for Cats to dogs). They are simply different doses of the same active ingredients (because of the species differences). Frontline for Dogs will still work on cats - but not at the same efficiency (towards the end of the month) as Frontline for Cats. Therefore you should always use the correct product for the species.
Depending on how old your cat is, you can use Frontline, which I would recommend. You could also use Revolution. There is a worming medicine, that is given orally. Frontline is also given orally. Revolution, however, is treated by squirting it right in between the cat's shoulder blades. With Revolution you do not have to worry about the cat licking it off themselves, it will not harm them in any way. For De-worming, you can get it at the vet, or at an animal shelter.
According to Frontline, it is safe to use Frontline Spray on puppies from 2 days old and Frontline Plus on puppies from 8 weeks of age.
