I'm so glad to hear that Tuna is home now. I hope that he continues to do well and that it's only a minor UTI if anything. Please continue to keep us updated about him.

Laura, I also wanted to add that because you mentioned that Tuna is a bit overweight, you might want to discuss his weight problems with the new vet. I've heard from other vets that the more overweight they are then they're more likely to become blocked and or have UTI's. I'm not sure why this is true but you may want to ask your new vet about this.
