I'm in a bit of a bind here. My Zelda is a 10 month old MC. I'm not sure how much she weighs as we don't have a scale, but I'd estimate she's at least 14lbs.
And we are having a big flea problem with her. We noticed a few months ago that she had become rather infested, so went out and bought Advantage flea treatment for cats over 9lbs, as well as a flea comb and flea spray for the house which we used liberally. The Advantage worked only very slightly to the point where there weren't as many live fleas and dirt in the comb (I flea comb her every day) for maybe a couple of weeks, but they always came back. As in it didn't seem to be stopping the breeding cycle of the fleas, only killing the current live ones.
So after spending $100 on that treatment I went to the local vet and got her some Capstar tablets. The vet said these should work well and may even help the Advantage work better but I had already used all of it so just decided to see how the Capstar did on its own. It seemed to work much faster and better than the Advantage to the point where she would have hardly any fleas for a couple weeks, but they always ALWAYS come back in full force after about a fortnight.
After using all the Capstar tablets, I went out in desperation and bought more Capstar and more Advantage (as I've seen Advantage recommended for MC's many places and it has good reviews) and gave her both the tablets and the gel. Still, they don't work for more than a couple weeks.
I am getting to my wits end here. I can't have my poor girl constantly battling fleas but I also don't want to keep loading her with medication all the time. With pets in the past I've just needed to give them their regular monthly or quarterly treatments depending on medication type and they would be completely fine flea-wise until the next treatment was due, and these were cats and dogs that went outside in the country every day!!
Zelda is an indoor cat (we live on the 12th floor), but occasionally I'll take her out for little outings down to the common area in her harness so she can have some fresh air and get some exercise. So it's not as if she is constantly going outside to contract new fleas. I want to take her out more often but I worry about the flea issue as they seem extremely resilient to treatment. We are in Hawaii currently so I don't know if maybe the fleas here are some sort of super duper resilient breed or something?
My mother in law who has 4 cats (one MC) suggested I bathe her in Dawn dishsoap as that's the thing she says works the best for fleas but I have serious reservations as I can't imagine that being good for a cat's skin? (tho MIL says she's never had a problem with her cats). And even if it would work, Zelda isn't a fan of the bath and I don't want to have to traumatise her like that unnecessarily.
Please I need help! What flea treatments have worked the best and for the longest for your Maine Coons? Thanks for taking the time to read all of this and for any advice you can give me
