I asked about thyroid and she said its VERY rare for a cat under 6 years old to have it but she'll check since he's a rescue and we only have the past owner's word that he's 3.

He's ready to come home from the vet, but I couldn't pick him up tonight, so he's spending the evening at the white coats.

I'm really worried about my handsome boy. He's such a sweet boy and now I fear he was abused based upon what the vet said about his skittishness and his eye..... he has no eye infection, rather, he has a sunken eye like he had a serious injury. Based on that and how the past owner tossed him out for simply scratching the jerk.... I wouldn't be surprised to hear he was abused.
