My BP keeps yawning..

Hey all, so I did a little searching around and know the occasional yawn is typically nothing. However I noticed when I changed my guys hide yesterday he did it a few times in a pretty short period of time, I also saw him yawn once earlier today then once more when I handled him today. I did notice yesterday he still had two decent lumps from his meal on Monday which I thought was odd, but gave him another day and he was fine today. I've read for RI's vets basically just say make sure temp and humidity are right and it'll clear up... Is slightly frequent "yawning" a cause for concern? The inside of his mouth doesn't look irregular to me, no wheezing, hissing or bubbley noses... :-/

Thanks,
Dev

He may just be realigning his jaw, a lot? I would keep monitoring him and watch for any tell-tale signs of illness. I haven't dealt with this myself but I think it is what I would do

I see this a lot if there's something stuck in there mouth, maybe give it look.

Whats a good, safe way to do that? :-/ Just observe closer, or..?
