Cat Allergies Treatment

So ive had 2 cats for the past few years but latly when i spend a lot of time in my house i sneeze a lot and my eyes begin to water hurt and itch, could this be from my cats? because when i went to a friends house these problems went away

my aunt has 4 cats. 2 for many years, the other 2 for about a year now. she lets them all over the house, on the furniture, etc. she doesn’t have allergies, but she has been sick for a while now and my mom suspects it’s a reaction to the cats. is it possible to develop allergies from cats you’ve been around for a long time or are there long-term side effects of living with cats even if you’re not technically allergic?

also ,are rabbits usually mroe gentle than cats? i mean cats are often scratchers and biters(not all but a lot), and u cannot leave them alone for very logn tiem periods, so is a rabbit a more friendly, gentler choice? can they also be friendly to humasn also? also, is it better to get it as a bunny? and how will i knwo if the rabbit is right for me?
sorry to talk that way of cats but my experience. are rabbits good choice?

I grew up with 5 cats and never had allergy symptoms until I went away to college and came back and developed some rashes. After a few days , they disappeared. Now (at 33) I just got 2 new kittens and my allergies are real bad (runny nose, sneezing, eyes, etc.). Is it possible that with time, my allergies will go away or is this permanent? Hoping not the latter, but may be a reality that I need to face. I’ll prb. head to an allergist butr looking to see if anyone had firsthand experience about this? Thanks for your help! Doug
