"-They CAN still produce joeys 4-6 weeks after the neuter" Inaccurate
It is NOT that the males can still produce after a neuter, they CAN'T. Females can hold a pregnancy in stasis for up to 12 months and give birth when she's ready or conditions are right. Sometimes, she gives birth a couple weeks after the male was neutered which make it seem like the male was still producing after his neuter.
Personally I prefer pom off lazer neuters as opposed to pom on traditional neuters. I feel they heal faster with less issues after the procedure, most of the time e collars are not needed or necessary.
If your not sure what method your vet uses, ask them and ask what their procedures are. Will he be sent home with pain meds, do they have e collars, etc... ask your vet....
neutering Does NOT reduce the mating urge if the male is already sexually mature when he gets neutered. However, if he hasn't hit sexual maturity when he is neutered he likely won't have a sex drive. So if the glider is anywhere from 2-4 months or older, has a bald spot he will still likely have a sex drive.
"mating wounds" DON'T only happen when mating, they are also called Dominance wounds, we still don't know the ACTUAL reason the wounds are happening, so now we call them NECK wounds. Males and females get neck wounds, females can give neck wounds so can males it's not gender specific.
Neutering also does NOT stop self mutilating nor does it break the cycle. SM has NOT been DIAGNOSED with a cause either, there are theories, but none of the theories are hormone related what so ever. Not all after neuter issues are considered self mutilating. Some just don't heal great, or a stitch comes undone or the glider grooms off the glue used to seal the site there are several complications that are not considered self mutilating.
I'm not sure where you got your information from, and I'm not trying to be mean or a know it all. However, inaccurate information needs corrected.
I've got pictures and actual self mutilating cases where a neuter did NOT stop the cycle and the glider kept self mutilating and some have died. The self mutilating was present BEFORE the neuter. There is one glider currently in medical foster care still healing and still has potential to self mutilate with out his e jacket and or e collar on.
Myself, and Several veteran glider owners with more medical knowledge than a lot of vets, that are involved in these cases and studies to find out why it's happening.
