I am not trying to come off as rude or snarky, so please don't take what I'm about to say as anything like that ok?! But a lot of people here have owned rats for years, myself since 2003 and I've been in your shoes with cages. My issue was no pet stores within 300kms, and no vehicle. I tried everything, EVERYTHING posted on the internet to make a big enough cage for my rats I owned at the time. Nothing works. Seriously, nothing. Cages home made will work until you go to wash them, something will always suck about them should it be smell, lack of cleaning space, rebuilding, fixing, dangers to animals living in them, cost.... you name it. Honestly hun, start saving up for a single CN and just use the cage you have now. I have 2 rat resorts here, I have 2 small boys and a male rat/mouse combo living in them. They are fine, with lots of out time. I would keep 2 females in a rat resort until I got a bigger cage for them, no problem. Please, just save up for the CN and take the advice from people who have been there. I do feel like some people want to say this, but are tip toeing around the subject. I will say it because I waisted so much money and time on home built cages, I could have bought 3 CN's with what I spent on those. Once you have a great built cage, although a bit pricey, you will finally see what others are saying. Again, don't take this in any other way than me just trying to be blunt to save you the heartach!! :heart:
