My Sugar Glider feels smaller?

I don't know if I was going crazy yesterday or something, but it felt like my Sugar Glider was "smaller" when I had it in its pouch yesterday. When I have it in there, I usually hold it around the waist(not forcefully, just holding it), and it felt like it was small, like when I first got her. I don't know if that's possible, or even a normal thing to consider being concerned about, or even if anyone else has thought the same thing, but it was weird.
She was doing what she usually does in her pouch: grabbing the top corner and sleeping, but this time she felt smaller. Usually it would feel like she was bigger. Any thoughts?

The best way to keep track of whether they are gaining or losing weight is to weigh them regularly. Whatever they weigh at the vet during their well check is a good baseline to use. Other than that, I can't begin to guess why she would feel smaller physically.

I can't either. I've never even weighed her to begin with, so I have no idea what to be looking for if I do weight her. She looks the same size, but yesterday in my hand she felt smaller. Maybe I was just being paranoid.

Your vet did not weigh her when you took her in for that emergency visit?

No, you should not just look at her and use that as your baseline. Weigh her regularly. Get a gram scale and begin doing so. Then, you won't have to wonder if you are going crazy or being paranoid. You will know for sure if she is loosing weight at an alarming weight.

I agree. I use a cheap gram scale that's made to measure food to weigh my gliders. I'd like to get myself a digital scale, but this one works for now.

No; the vet didn't weight her when I went in, he just looked at her. I'll try to get my hands on a digital scale, or maybe one that I can use for my rabbit as well, who just eats and sleeps all day. And even if I did get one, I would still have the paranoia before weighing her, saying to myself: "is it going to be significantly lower/higher?" It doesn't stop. But I think it's because she's such a small animal and they're easier to be greatly affected by small things.

Most vets always weigh on a gram scale. You can get a gram scale at most grocery stores and Target/Walmart type stores.

Well I've only taken her to the vet once, and he didn't weight her, and I've only had her since September 4th of last year. I'll make sure she's fine, and I'll try to get that scale as soon as I can.

if you have big lots near by the also sell them (sometimes) and are much cheaper if they have them. Bed Bath and beyond usually has a few also

I got mine on ebay for less than $8, even with the shipping.

Yeah I may just get one from Target today if they have any. I'll be sure to weigh her once I get back, and check every day to see if she is actually losing any weight.
