So my black rat makes what i can only call "very quiet basketball squeks" usually when shes investigating or walking on me. I assume this is a nervous thing but i don't know. She also clicks sometimes while doing this.
my violet will make scooch-y sounds when she's excited about something that she smells. but not being there to hear exactly what your's is doing it might be different. a myco flare can last a long time and the longer it lasts the less likely your rat is to recover so its always a good idea that when in doubt get it checked out. if she is showing any other signs of illness other then an odd sound once and a while i would most definately make an appointment with the vet.
My Jackson Rat does this all the time I call him my huffy rat. He doesn't do it any other time but when he is digging in my blankets or trying to dig his way out of my arms. *shrugs* he is just a huffy rat LoL
Omg! I'm so glad you posted this because one of my rats does the same thing.. or at least it seems the same. I posted about it a while ago, but I don't think I was able to describe it very well.
Is the "scooch" sound soft - because that's sort of the noise that Sachi makes. Hers is somewhere between the "very soft basketball squeaks" and a soft whimper. She only does it at night though, usually when she's eating.
Keep me posted, lets keep comparing! In fact, I recorded the sound on my computer, I'm just trying to figure out how to share the file.
