My ex was allergic to cats, and when we got our cat, Lock, we fed him a raw diet (which my vet said would cut back a little on the allergic reaction, as most are allergic to the dander...which is in part related to the ph of the saliva...which is in part related to the chemicals in their food...I hope I got that right, haha). We also added this supplement to his meat and water that helped level out his ph. I wish I could remember the name of it, but it's been a long time.

Chris took allergy meds when he needed to and always washed his hands. It worked out well and he was even able to cuddle with Lock. But, as soon as he'd walk into a different house with cats, he'd be miserable. I really think the food we fed Lock made a difference.
