My 6mo. old Pomimo has been displaying weird behavior these last few weeks. I thought it was heat symptoms but she hasn't really bled at all. She seems fine in the afternoon/evening all thru night but everyday around 9am. she starts this anxious state which includes restless legs, clingy, wants cuddles and tummy rubs, and doesn't seem to want to eat, drink, or go outside... she resumes her normal happy go lucky, spunky, self, becomes ravenous and thirsty late afternoon. I try to pay extra attention and comfort her but it doesn't seem to work that much. What could it be? Any ideas?
