Finding housing with two cats

Hi all! I'm having a bit of a problem and I hope some of you who reside in Norway can help me out and kindly share you experiences with me. I got accepted to University of Oslo and Arctic University (Narvik campus). I own two cats that I'm not able to leave back in my homecountry. I'm also in the process of applying for Nord University (Levanger campus). I did ask student housing association in both universities I got accepted for about the possibility of having pets, and Oslo one said that it's possible only if I need to have pets for health reasons (I don't). Arctic University said that there's only one available student housing (a big 2 room apartment) which allows for pets, but it's not in Narvik (also, I'm going to move alone and don't have enough money for an apartment like this). I'm really not able (and don't want to, they're my family and best cats in the world) to leave them with anyone so I'll be looking for housing on the private market.

I looked around finn.no, and it looks like big student houses with single rooms for rent, shared bathrooms and varied prices depending on the number of people in the house are popular here, no matter the city. Do you guys know if I can assume that pets are not allowed in places like this? Since there's probably high turnover of roommates who might be allergic etc. Looks like it only leaves me with single studio apartments for rent (I don't have enough money to rent most of them :D) – do you guys have any experiences with landlords allowing pets in studio apartments? I've read on most notices that pets are not allowed, but maybe you can usually work something out with the landlord.

As you can probably see from the post, I'm really confused and unsure of what to do, so I'd appreciate any help I can get. I'd hate to have to give up on my dream of studying here for financial reasons or because of my pets. Thank you for the help in advance!
