Ms Butter (Grey, 9-10 wks old, healthy) has been shivering and chattering her teeth just like she is cold. She is warm to the touch, but is firmly planted under my hair on my shoulder. When I put her on the cage top to "Play Fight"; daily ritual, she just jumps right back to under my hair. Is she okay? Do I need to get her heating pad out, before I have to go to work at 2pm EST? Thanks for any help; she is my first. (She did take 20 mg of formula this AM from Rick; my better half, so she is eating okay and I feed her brocolli and rodent block &/or monkey biscuits.)
