Pet's info: Cat | Mixed Breed | Female | spayed | 6 lbs
We tried a new topical flea treatment on our cats, Cheristin. 2 out of the 3 were lethargic for the first day, I assumed due due to some relief from critters. However, my smaller Tabby cat is still very lethargic going into day 3 after application. She has always had skin issues but seems to be more sensitive to touch than usual. She is still eating and using the restroom, but is otherwise sleeping in an isolated spot when she is generally the most cuddly of them all. Should I be concerned?

Yes, I would be a bit concerned. Unfortunately, not all medications work well on an animals. I would consider this an abnormal reaction. I suggest you wash her with some Dawn Dish Soap to remove all the residual product from her body. If she stops eating or using the bathroom she needs to see a vet ASAP. I recommend you use a different product on her from now on. Maybe a Seresto collar? https://www.petco.com/shop/en/petcostore/product/seresto-flea-and-tick-collar-for-cats
