I'm super super worried about my rat Poppy. For a few week she has been struggling. Having trouble breathing, becoming less active. But today, I came home from school an let them out, after a while I realized she wasn't exploring, but hiding under my blanket... This was very unlike her. She's super skinny, an I tried to put her on the floor but she just climbed up onto the bed again. She is there year old. My room I very hot and stuffy but it does not see to be affecting the younger ones. I gave her a wet cloth, a froze bottle of water, an a bowl of ice water, what else can i do? she is breathing heavily and I snuggled up to me... I'm very worried.
