So I was asleep abd my cat was asleep on top of my gecko viv next to me. I heard her be noisy and then she fell, it was dark so idk how or why she fell and I could see how she landed but she started panting and is now just sat on the floor. She's stopped panting now but every few minutes I hear her take a heavier breath. She is loafing now on the floor but I'm still worried since she's quite frail, she's 15 but has the body of an older cat. Are there any checks I need to do? Should I take her to the vet tomorrow? I'm pretty worried and idk if I'm going to be able to sleep now-
