Sorry if this has been addressed! I'm new here and I took in 4 month old kittens who now have fleas again(Advecta)didn't work long and now I discovered these brown rice spots where they lay! I mortified! I can't afford hundreds of dollars in vets visits. Is there a good all worm medicine I can get OTC? Will these hurt me and my kids? I've never dealt with this before. Will my kittens die? I want something I know will work and fleas meds too? Thank you for reading
