So Isis and I are currently lying in bed, with her on my chest, and I can hear her make a swallowing noise every few minutes or so. Is this just her swallowing saliva and is it normal? Also, she's purring, and I can hear air going in and out of her nose occasionally. She seems healthy, but I wanted to check before rushing her to the vet. This stuff happens often. Oh, one more thing: sometimes when she eats dinner too fast, she starts hiccupping, should I be trying to slow her eating down at all?
