I don't know what size your cage is, but I have a 2 level also with a ramp. I bought a 6x2 C&C cage with a 2x2 hayloft with a ramp kit from this site. I have 2 girls, Cuddles and Buttercup, both are around 4 months ( 2 weeks apart) old. The both LOVE the ramp ! After a couple of days of being in their new cage, I enticed them onto the ramp by placing a small piece of fruit half-way up the ramp. Grapes happen to be Cuddles favorite fruit so she took the bait first. Then, I put the other half of grape on the top of the ramp. This drove Cuddles NUTS !! She wheeked and wheeked for me to give it to her. ( I know, I know, I very nearly gave in !!)
However, I stayed strong and just kept encouraging her, pumping her up, and slowly--she crawled up, crouched really low and inched her way up !! Hooray ! Then, upon witnessing Cuddles bravery, Buttercup wasn't long to follow after ! ( although Buttercup did need some encouraging too but just a little)
I am glad that the ramp was brought up though. I would like to say that recently I had a huge scare when Buttercup decided to jump
over the side of the ramp, from the
TOP of the ramp !! So, if you have a piggie that loves to jump,
please add higher walls to the edges of your ramp ! The ramp that came with the c&c cage kit from this site,
does have about 4 inch sides ( looked for my tape measure to measure it couldn't find it) but I
had to add 5 inches to keep Buttercup from jumping off the top again.
A piggie on here died recently from a fall. So,
just to be safe I would make sure your ramp has walls, if it is to a high second level, like my cage is. If your piggies are young, there is no way to tell if they are jumpers yet. I was lucky, Buttercup landed like a cat and was not hurt.I should have known better though, because (sigh) I knew she was a "jumper".
For when Buttercup would run down the ramp she would jump half-way down forward and I thought it was cute and called her my Olympian. She has always popcorned really high and she loves to run really
fasssst.
Good luck and I am sure that your piggies will thoroughly enjoy their new cage and added space !
