So me and my friend were looking for a rack system on Craigslist and we found a post for one and it came with a BP.
So we thought it was a good deal, till we got both items. The rack system was...horrible but we managed to make it work after fixing it up.
After seeing her set up and her, we just had to take her.

We noticed a lot of things while we were looking at her closely.
She was obviously really neglected...

Here is some pics we took:

So I am posting here to see if anyone knows what might be wrong? The two front vents look blocked and we noticed that she whistles as well...
So any advice on what we can do or why these are closed up or if she is starting to get mouth rot?
She was also severely under weight, the guy was feeding her medium mice and shes supposed to be close to 3 years old now.

So far we've set up her home, gotten her water and a medium rat, which she eagerly accepted.
We plan on taking her to the vet asap but wanted some advice till we do.
