Oh man, I feel you. Worst thing for my last cat was he had to get radiation therapy for his hyperthyroidism. So he had never been away from home overnight and they have to keep them like 4 days until the radiation is out of their system enough to come home BUT they say no cuddling or sleeping next to them for another 3 days. He was SO SAD when I would push him away to the other side of the couch and when I had to lock him out of the bedroom for the first time ever.
