Gecko squeals randomly?

[Brachiosaurus]

Hello! So a few months ago (4) I bought my second Leopard Gecko and they randomly squeal? It’s not chirping or barking or screaming so I have no idea why. Just random little squeals for a few seconds and when I check on them they’re just chilling so I don’t know if I should be worried?

Are they housed together? I know that if my girls are out together they get squealy if one gets in the other's personal space. Squealing is a sign of defense so if they aren't housed together there must be something spooking them.

I forgot to mention The other one passed away three years ago so it’s just Tangerine. That’s so bizarre I guess I’ll keep any eye out for anything,

Oh I'm sorry about that.

That is pretty odd. If it were a squeak or chirp I would say it's normal. I'm thinking if your husbandry is all correct and there is nothing that would cause your gecko to become spooked or make that sound, then I would say that it's "squeal" might be your geckos version of chirping/squeaking, especially if they're still young.
