Jato was neutered about 2 months ago- he had an undescended testicle, so he had to have (2) different incisions. I dropped him off in the early morning, and brought him home later that same evening. He was very tired and groggy that first night and most of the next day. I slept on the couch with him in his little bed beside me. I put the baby onesie on him, and he did fine. If you use those, the boys should be able to sleep together like usual. I have not noticed any difference in his behavior or personality. Like you said, it is pretty routine surgery- I'm sure they will both be fine.
