I agree the cats are never done scratching and that pound shop spot on doesn’t work. I’ve two cats and from they were young they were fleaed wormed and neutered. My choice I keep them in too many cars flying about here but they are well cared for. She feeds hers salty ham never ending treats and rarely any normal cat food. Where is the cat meal for their vitamins etc. she doesn’t have a clue. She’s never done scratching her self I’d say her house is jumping with fleas. There’s her cats and all the strays mix in together. Again stupid animal ownerAnd another thing never mind the cats spraying that house will be full amd I mean full of fleas no matter how many times she uses pound shop spot on. Letting other ppls cats into the house and feeding them pure crap I'd be fumming and contacting rspca if it was my cat.
