Question from Debbi Lee

Can Frontline Plus for Dogs be used for cats, as long as I adjust dosage and give correct amt to cats? ... Is there anything in Plus for Dogs that would harm my cats? Thanks.

Our Vet Says:

Frontline Plus has the same ingredients for cats and dogs but the quantity is different between the two species. Both products, Frontline for cats and Frontline for Dogs, have fipronil and S-methoprene as their active ingredient. As you probably know fipronil is a powerfull insecticide which will kill all fleas and ticks, and S-methoprene is a growth hormone regulator which is breaking fleas life cycle and stops a new generation of fleas to be born from the eggs and larva found on dog or in surrounding environment.
Below is a small table to make it easier for you to spot out the differences.

The second problem is that a cat needs 0,5 ml solution which is very difficult to measure from a dog pipette because they do not have any gradation on them. Theoretically from a pipette of 4 ml you could treat 8 cats but the risk of side effects increases with overdosing. Overdose application of the product will cause a sticky appearance of hairs at the treatment spot. Among the rare adverse reactions are  transient skin reactions at the application site (scaling, local hair loss, itching, redness) and general itching or hair loss have been reported after use. Excessive salivation, reversible nervous signs (increased sensitivity to stimulation, depression, other nervous signs) or vomiting have also been observed after use.
In conclusion you have two reasons not to use Frontline for dogs on your cats. I would like to advise you to look for a flea product for cats, there are other cheaper products available.

My Maddy is 6 years old and a HUGE girl -170 lbs. and the sweetest girl in my world! Trouble is... She is miserable with the itching. I been to the vet and tried changing her food to no beef, chicken, or pork. I also had her on allergy pills that cost $140 a month. I simply can’t afford that plus the expensive dog food, plus continuous yard treatments, etc. can you recommend a flea pill that is affordable? She is also on prion for incontinence. Will it affect that medication too? Thank ...?
