Day before yesterday my squirrel made a bird like squeaking sounds but in high pitch like she was just at home chilling and she suddenly made a sweet squeaking note and we all thought it's because she was happy. Yesterday she made that sound again but twice and today she doubled them more and kept squeaking, i didn't notice any kind of discomfort or threat around her..she was happily roaming around and just makes that noise out of the blue?? Why is that so? I went through google to know but i just couldn't find any. Is it a mating call??? Or ? It's just because she's happy?��
