Sherbert keeps "posing" like he wants to go to the bathroom. He uses a litter box, and today, catching him trying to go pee/poop (I have no idea which), I immediately changed his litter box concerned that it might be full. Didn't help. He is posing everywhere. I must add, nothing has come out. No urine, no bms. I'm thinking may he might have a urinary tract issue - how immediate do i need to take action? It's Saturday night, can it wait to take him to the vet on Monday?? I"ve also noticed that he seems to be losing weight. He is on weight control food, don't know if that is why - he's been on the food for maybe 2 yrs, the weight loss is recent.
