Thanks everyone. Pearl's left eye still looks terrible but she's been much more active today and also very vocal. I can already tell that she's feeling much better. Luckily I'm off until Jan.2nd so I can watch over her and give her the meds she needs. I know that Siamese cats are known for very poor teeth but I hope that in Starr's case it's nothing serious and that he'll feel much better after his cleaning.
