hi all, my Genna had an ultrasound today cause she was straining to pee and there was blood in it. the vet says she has no stones just sludge and a thickening of the bladder wall. my question is there a good dry cat food to feed her? i want to be informed when i pic her up from the vet. she is currently eating instinct rabbit which is a grain free dry cat food. is that ok? she hates wet cat food so that is not an option. i know my vet will push science diet which i am not fond of so if i had other options to discuss with her that woud be great. oh sorry i wasnt sure whether to post this under health or nutrition. thanks for any opinons!!!
