So my little ones didn't have fleas when i got them and cleaned them, but i live on a yard and they are housed in a stable and there was a feral cat that lived here for a while when my other cat died (we chased it, i didn't want it sticking around because i knew i would get kittens again) but it seems to have infested the hay with fleas. I can't get rid of the hay because i need it for the animals, but what would be the best action to take Re the kittens? I have used a generic flea powder that was suitable for ktitens but i can't see it being very effective for long, so i was wondering what other SAFE measures i can take?
They are still very young, supposed to be 8 weeks but i would guess they are maybe younger. Any help appreciated
