I have received a few requests for an update on our sneezing cat. First of all I really, really appreciate all of the responses and advice that was given. You all are very kind! I looked at all of your solutions and researched them on the web to see if that was the problem.
He wasn't feeling any better a few days after that last post so I took him back to the vet. We saw a different vet this time and she really looked him over- in the ears, nose, mouth and we even ran a few tests. The good news is that he doesn't have Feline HIV or leukemia. I was really worried about these two diseases because we have another indoor cat and didn't want to spread those to her. On the other hand the vet thinks he has feline herpes (to which my boyfriend at the vet replied, "see I told you I got the herpes from the cat." He was kidding of course, he doesn't have herpes, but the vet thought it was funny.) Feline herpes is spreadable too but since the two cats don't share anything or get too close to each other, I'm not too worried at the moment.
I guess there isn't a good test available for the herpes and there isn't a whole lot you can do for it anyway. But if he does have it, it compromises the immune system so it will take him longer to get well. Actually, I think herpes is a pretty good guess because all of the symptoms match this link.
The vet gave us an antihistamine to try to dry him up so I gave it to him over the weekend. It made him super sleepy so after 3 days, I stopped the meds to see if it was any better. It seemed to work- the sneezing was quite less and he wasn't coughing at all. A couple of days ago he started really sneezing again, so I gave the meds to him and he was better. His appetite has improved tremendously and before the second trip the vet, he wasn't really wanting to eat- now he wants food every three hours which is great because he is underweight. It looks like this isn't curable but since I work from home, I able watch him closely to monitor any changes and then treat it right away.
I somehow came upon a website that says that you can improve a cat's well being with a raw meat food diet. I would like to try the Nature's Variety food and was wondering if anyone out there has their pet on a raw meat diet. Any likes or dislikes about raw meat for pets? Thanks! -Sarah
