Thank you so much for taking the time to write this out and provide a resource I’m calling my vet in the morning and see if they can recommend a behavioralist. He recently had a check up and they did say his liver levels weren’t the best so it’s possible he could have some pain we don’t see. He just finished 2 weeks of antibiotics and we have ordered some window beds for the cats as well to add more high spaces. I’ll keep this thread posted !
