Things you can ask your vet...
1 What method of neutering do they perform ? Traditional pom on ( sometimes they will do traditional pom off but you may have to request it ) or Lazer pom off.
2 Do they send any pain meds home after the procedure?
3 Do they have glider e collars in the event the glider needs one? E collars are a better option than e jackets for neuters.
IF not you may want to get the supplies and make one so you have it on hand if you should need it. For neuters and tail injuries the best e collar is the shot glass style, the directions and supplies are on the link below.
They are easy to make but can be difficult to put on especially if it's your first time. Somewhere I have a video of how to put it on easily if I find it I will post it.

If you DO need to use an e collar ( for any reason not just neuters ) There are some after care while the glider is in the e collar.
Like making food and water accessible to the glider with the e collar on for this we use bird water silo's for their liquid staple and water the silo fits in the cone so the glider can eat on it's own. The pouch needs to be accessible to the glider with the cone on, we suggest using Open Environment pouches for this instead of traditional sleep pouches. Clean the inside of the cone with cute tips and water because it will get messy. You may also need to "groom" the glider from the neck back because it won't be able to self clean, just use a damp paper towel or tea towel to groom them.
If you have any questions about any of these items please ask, I'd be happy to post links and or pics for each item.
Neuters aren't as risky as they once were, vets have more experience with them now a days. The risk is higher for older males ( 9 yrs and up ) because of the anesthesia, not the actual procedure. However having said that, it's always wise to be prepared in advance. The procedure itself only takes about 10 to 15 minutes. Usually the glider is back to it's normal self the same day or the next day.
Personally I prefer the lazer pom off, this method heals faster with less chance of complications. But really that is just my personal preference
