Well yesterday afternoon when my husband went home for lunch Boris was much worse. We made a vet appointment and took him in last night. The vet tried, but basically she said his respiratory problems had come back with a fury. We could try a stronger antibiotic, but as weak as he was (unable to lift his head and in obvious pain) there was only about a 30% chance that it would work and even if it did he would probably have a life of chronic issues with continuous antibiotic treatment. It was very, very, very hard, but we knew what we had to do. He was such a little sweetie, in spite of the pain he was in when I picked him up to cuddle him before they took him away he started bruxing. I will miss him sooo much. And Figaro misses him so much! Usually when I take him out he stays on me but he'll climb all around me and try to play. Last night he stayed on my shoulder for 30 straight minutes just chattering and giving rattie kisses and squishing as closely against me as he could, poor fellow. Right now we don't have any other males, so he's all by himself.
