What medications are you on currently? Right now I take Zyrtec and I highly reccomend it. Also try flushing out your sinuses a few times a day with a saline spray it will help to remove any allergens that are stuck to your mucus. I also love Nasacort as a daily allergy nasal spray. Try washing your sheets in hot water at least once a week that should help. While it sounds mean, it might also be helpful if the kitty doesn't go into your bedroom. I use wet cloths on my cats once a week to help wipe up some of the dander off their fur. I hope these suggestions help.
