Burlington had his recheck today

He's just had an occasional sneeze, but no nasty gross discharge. His appetite is good, he demands food all the time (he wants more canned but my wallet says he's getting enough!). He's been drinking from the fountain, too. So we went in today for his calicivirus booster and he's gained a whole pound, up from 9 lb 3 oz to 10 lb 3 oz.

Big brother Trevor had a calicivirus shot at well, and he weighed in at 16 lb 3 oz. That is down from what I weighed him at about a year ago (18 lb) but I don't know...he seems bigger than he was but it may just be because he's so much bigger than Burlington. He's not had as much as a sniffle or anything, he's a strong, healthy boy!

Yay, healthy babies! Your sneezer may just have some minor allergies. If you're feeding him any amount of dry, make it a grain-free and preferably limited ingredient, and see if it doesn't improve. It could also be environmental/seasonal allergies, just like people!

Those are BIG kitties. Are they Maine coons?

Yeah he's on Earthborn, the dry variety right now I think has some grain, I usually buy the Primitive Feline, which is grain free but the store was out of that last time I was there. The canned is all grain free though. 

Burlington came from the shelter, and he looks purebred to me. Trevor came from a garbage can when he was 4 weeks old, he's not purebred but he's definitely got some MC in him.
