Some solid advise I here but first I’d like to make clear I’m not a vet doc but I do get asked a lot at the club to handle members animal problems quite a bit and I concur that cats don’t need to be eating grapes for the reasons aforementioned and it’s a lot of trouble to pump its stomac but I have a simple easy solution and it’s simply a dung beetle. Get you a dung beeetle and the cat will eat it and it will eat the cats poop which has the raisins in it and problem solved
