I have two cats and am sensitive to them. I found out when my first cat of 18 years died and I was without a cat for over a year. The cat had been an outdoor cat but then got sick the last year of its life so spent more time inside and with me (in my lap) and I'd get hives most night and stuff. All that went away after he died but my elderly neighbors got a kitten and I went to see it, didn't stay but 5 minutes but broke out in hives soon after getting home!

These two cats were difficult for awhile but some people get use to one's own pets over about six months and I'm okay with them and put up with the extra congestion. I just make sure I wash my hands after any time I pet or play with them and make sure my bed is made so my little girl can't sleep on my sheets but stays on the spread which stays away from my face at night. My house is not great/done well for my other sensitivities, "mold" and dust; I'm carpeted throughout with cheap carpet (want to replace it with wood some lifetime and only have a few rugs) and my husband smokes but I eat well and take supplements and work at making my health better and that makes everything across the board better. When I don't take my asthma meds like I'm supposed to that gets worse, etc. I think everything is connected to everything else so if you can improve something a bit in any area (that's easiest) it might improve your stuffiness situation too.
