I know someone that is getting rid of a cage they were using for kittens and I was wondering if it might work for my 2 girls that only weigh around 2.5 pounds at 6 months old. This is just like the cage http://www.petedge.com/catalog/prod...ateType=1. I thought if maybe I could build some ramps and possibly have to make some resting places this might actually work for them or would it be too small? The dimensions of the cage are 35 1/2" L x 22 1/4" W x 48" H I figured if this would work it would save me some money and time trying to build a NIC cage.

That looks too small and some bunnies are scared of jumping up and down if they feel it might be too steep. I would just make an NIC cage. It is really worth it. I created a 3 story condo for $70 dollars, which is a lot cheaper than a pet store cage. That way, you can make the NIC cage as big or roomy as you need and your bunnies have enough room to hop about and periscope.

I agree with chacha. Another alternative is an xpen ( exercise pen), I use 2 for my bunnies,but 1 with ample play time would work. You can get them for 50-70 bucks new, and often cheaper on Craigslist.
