Aw, Kanu, they are so cute! Look at those fluffy faces.

Norwegian forest cats are amazing. It's the bad breeders one has to look out for though. I briefly owned a NF kitten a few years ago and it didn't end well...

And allergies can come and go...And with correct medication one might be able to control it. It depends I guess. And there are some breeds, like Russian Blue, Devon Rex and Siberian Forest cats(very similar to Norwegian Forest cats) that are claimed to be hypoallergenic.
