Hello, I have a 1 year old Flemish I adopted. He was very overweight when I got him but if cut the junk the previous owner was giving him. He has been doing great and always using a litter box for urine and only occasionally droppings outside. 2 days ago I gave him 3 strawberry tops and 1 blueberry as a treat. Since then he has peed substantial amounts outside the box on the floor. I cleaned with vinegar. It has only been a couple days but has anyone heard of those items triggering a bladder issue like that as that was the only change. I was doing some research however and have realized I have been giving him too much Kale so am not wondering if it’s a bladder issue because of the calcium although very coincidental with 2 new items?? Any ideas and if he has had too much Kale is there a dietary solve? Thanks in advance!
