This morning I woke up to my sugar glider making angry noises, so long story short her toe was stuck in her pouch and I got it out but now it's all red and swollen and she's having a hard time climbing her cage and I'm scared and don't know what to do

1st check to see if there is any string wrapped around her toe, if there is get it off. Take her to a glider experienced vet so they can determine if it needs amputated.

Is she bothering the toe at all ?

examine the inside of the pouch if there are any exposed threads that can't simply be trimmed removed the pouch and give her a new safer one.

Does she have cage mates ?

do you have a spare temp cage?

This happened to my glider as well and is pretty common because of their long nails. I now try to clip her nails more often. Also, are her pouches made of fleece? Some materials tend to catch their nails more than others. This is certainly not meant to place blame but to learn from. I had my glider for months before learning that I was using the wrong fabric. Anyway, I would definitely get her checked out by an exotic vet (at the very least, a phone call for advice). Not cheap, but better safe than sorry. Good luck!

trimming nails is a must.
The safest material in the world isn't safe if their nails are neglected.

Trim the nails.

She doesn't seem to be bothering the toe at all and I think it's gotten less red as the day has gone but I'm still worried. She does have a cage mate (aristocrat) but he hasn't really been bothering her. I don't have an extra cage and her pouch is fleece. After I found her I let her be alone in the bathroom all day so he wouldnt hurt her more being in the pouch with her. I'm afraid she might bite off her toe, but then it also doesn't seem like it's that bad at all, but I'm still worried.

ok, try gently rubbing her foot to get the blood flowing back to the toe. You want to keep an eye on the color of the skin of her toe, if it starts turning black over the next couple days, it is necrotic ( dead tissue )

She won't let me touch it, I got her on the floor and distracted her with a treat and got to barely cut the nail, but after that she won't let me touch even the nail. Should I put an e-collar on her?

Do you have one?

If she is not bothering it, let her be, no sense in cause her undue stress.

If she seems to start bothering it then yes put an e collar on her. But if you do you will need to make sure she has access to water and food with the ecollar on or hand feed her through the night.

I googled it and made one, but like you said I don't want to put unnecessary stress on her. I don't think she's bothering it, but I'm scared to go to sleep if she starts bothering it. I don't want to wake up to her toe being gone

can you upload a pic of the foot and the e collar ?

better yet if your on facebook add me there it's easier to talk on there so are pictures https://www.facebook.com/carla.sloan.1
