This is a HUGE thing!
I fed primarily dry, while occasionally adding wet when i got it at the store. one of my cats ( ive got two), Hobbes got a UTI and had to be on Antibiotics for a few weeks before he looked like he was improving. I moved them both over to an entire wetfood diet ( the REAL good stuff), and havent looked back. They seem happier for it too.
Dry food sucks. IMHO. And i also think it makes cats overweight too. ( i only feed them both a half can a day of food, sometimes a whole can *spread out over two feedings during the day* if i wont be there the next morning to feed them straightway) Both maintain good weight, and both are in great health according to my vet.Not too fat, not too thin
Hobbes is doing great now, and hopefully we wont have another occurrence EVER. Man did i feel bad for him.
