Ok besides my boys Scooter & Casper there is also stray cats outside. There are a total of 8 cats only 2 are females. Although 1 of the cats I think belongs to someone and just goes around the neighborhood. When I saw him the other day he had a flea collar on. 4 of them stay on my back porch they have a nice set up out there. Which I will be redoing soon for winter so they can stay warm. My back porch though enclosed cause it’s where my washer & dryer are. Anyway though enclosed it’s not properly insulated so whatever the temp is outside it’s the same on the back porch. So they will be getting a kitty house to stay warm. Anyway I think at least 2 of the cats has fleas. 3 of them are kittens about 6 or 7 months old and one is 1 years old. They will not let you pick them up 3 of them will let you pet them but you can’t pick them up. So a flea collar or liquid is not an option. Is there an affordable oral flea pill? Something safe for them that can be mixed in their food?
