I just had my little man neutered last wed - so i'm gonna try and tell you some of the things i wasn't prepared for (regardless of all the reading).
Before - just do what the vet told you as far as no food after 10
Now after - (is this pom on or pom off neuter?) He'll be really tired when you get home - I set up a small cage in my room and I asked the vet to put an ecollar on to be on the safe side (mine was pom on). Because of the collar he couldn't really lie down or cover himself up. So I was up all night making sure he was warm and that the collar stayed on - I also left the light on all night to try and keep him from being too active.
I feed HPw and pureed fruits and veggies so after they thawed I used a syringe one night, but the next night I held a teaspoon for him - it was just getting too messy with the collar - so see what works for you.
I hadn't seen the surgery site until late that evening, and it freaked me out a little - he was shaved and his pom was..well.. dangling - but after remembering that the area was very numb it explained why. I think it mostly caught me off guard because they have so much thick fur - who knew what was under there lol!!
My little man would not/could not sleep so first thing, 7am i put him back in the zipper bonding pouch and he slept fine all day long - I figured he really needed some good rest. He was on me for about 8 hours - altho some gliders do get up to pee during the day he really doesn't.
On day 2 - early afternoon, since the surgery site looked good I took off the collar and put him back in the bonding pouch so I could watch him very close -he cleaned for about 15 minutes and right back to sleep. So a few hours later I put his wife and kid in the pouch with me too so I could see how they would behave and everything was fine.
I know I wrote a book - but as i said, i did months of reading but I was still a nervous wreck. Many glider slaves put them back in the family cage the same evening - so that is entirely up to you. I know everyone has their own experiences - I just have a tendancy to side with caution. (I'm a big baby)
