I find them quite "hypo-allergenic" but don't know that everyone would...I would suspect that they would be the very best for a person with allergies...I couldn't believe it when I didn't react at all to over 10 cats in their house and most of them in your face wherever you are. I also usually react to cats saliva but don't with these guys. Could be coincidence though. I would recommend them....I just love them! But they do take some getting used to...and your house needs to be a comfortable temp...our guys were kept in a very very very warm house (which is not necessary) so have had to adjust over the last week to our meek 74 as compared to over 84+...they sure couldn't have reef tanks!
They do well at 70-74 so a normal house...unless of course you have reef tanks and try to keep the room cool...
so the tanks don't overheat!
