so i spoke to my vet on the phone, he said they might just be bored with the hay,and that all the branches they eat should wear down their back teeth fine, but to try massaging the jaw line and see if there is any pain reaction... ok no problem.. fluffy just kinda looked at me funny, but bun bun apparently luuuurves her face massaged.. she fell asleep! and when i stopped, she looked at me and nudged my hand like a dog..lol so i guess this means no sore spots...
