In some cases, yes. Advantix II is one such that is safe for dogs but extremely dangerous for cats. The active ingredient in Advantix and some others is permethrin which is perfectly safe for dogs and humans but deadly for cats.The cheapest thing to do for fleas and ticks is a seresto collar. It lasts for 8 months. Although they cost approx $60 dollars they currently have a $15 rebate for each one you buy.
That's what I did this year with my crew.
My next favorite thing would be Nexgard but that would run you approx $17 to $20 a month depending on the weight of the dog.
Make sure you research any home remedies you try because a lot of essential oils and other remedies can be toxic to dogs and cats.
We all like to cut corners but flea control should not be one of the places that we do.
Never use anything intended for dogs on cats. It can cause seizures and be fatal.
In the cases of Advantage II and Frontline along with other products that use the same active ingredients, the formulas for dogs and cats are basically the same, its the dosage that changes. We've been using Advantage II extra large dog for all our varmints, dogs, cats, and ferrets, for years. We just use a syringe to measure out the smaller doses as needed. That right there is the key, its the dose and not the product that is of concern.
And while the Seresto collars work great, there have been a LOT of reports of pets being made extremely ill and dying from them. Last I heard, there is a possible recall and ban coming on them.
