Had to leave him behind! I'm so upset, I've never had to do this before! He weed himself on the way there, which is so unlike him, as he never wees anywhere other than his litter tray. The vet is worried, she is doing test for his kidney function I think and for EC - but he is being sedated to hav ethis done.
I am going back in a little while to take him some of his own food and his unicorn so that he feel smore comfortable when he wakes up.
I'm crying I'm so worried!
