Yeah, my foster kittens used to have upper respitory all the time. It is very common. I checked on him this afternoon. He was just as friendly but his eyes were so goopey, they looked awful.
I should clarify, my weight problem is on the other spectrum. I have lost too much and look terrible. When I went to the Dr for my last sinus infection, I was down to 98lbs. I always lose weight with an infection b/c my body reacts to infection like I have a stomach virus and I have trouble keeping food and liquid down. Then when I get my meds, the meds make me sick as well. Therefore I have about a month of struggling to eat, making me lose weight. After my infection was over, I ended up 95lbs.

Then last week when I went in again due to the yeast infection from hell, I was 94lbs.

SICKENING!!! My big concern is if I get a sinus infection again and have not gained my weight back, I will drop close to 90lbs. That is disgusting.
My husband is trying to get me to eat more. He says I need to stretch my stomach out again. I can't seem to eat much at a time; I get full so quickly. I am also not eating enough for the amount of exercise I am getting. I fast walk (sometimes jog a little) with my dogs almost everyday. If someone would go with me and take the 2nd dog, I wouldn't have to go twice.
