Well, here is my first question to all the wise cavy slaves on here! I built my girls a ramp and a second story 1x1 loft on top of their 2x2 cage (it will get bigger, check my profile for details!). The problem is they won't use the ramp! I don't know if they're afraid of if it's too steep, etc. We've tried luring them up with food and treats, setting them up there, and doing all kinds of things. They'll come down the ramp just fine, but will not crawl up it more than a few baby steps. How can I show the girls that it's okay to go up and have a rest up top? Attached are two pictures of the cage/ramp so you can see! Thanks in advance for any advice!
