I'm pretty stumped on this.We just got a C&C a few weeks ago and we love it...until now! Well, I still love it but we're facing a big problem. Arlo is a VERY big boy. The vet said he was 4 1/2 lbs, close to 5lbs (but said he was healthy as a horse, just really big!) Being the normal boy he is, he keeps gnawing on the cage because he think he can get to the girls (we have a small place so the cages are close to each other). Well, Arlo can lift up the boys cage, and pretty easily I might add. He hasn't figure out how to get under yet, as it immediatley falls when he tries, but the other little guys can. I have no idea what to do. I also don't know how he got this big! I follow Ly's charts as best as possible and even modifed my meals a bit to put him on a diet. Before that, he got the same as everyone else, and none of them are even close to his size. It's pretty bad that he's that size, and my son when he was born was 7lbs! Only a 2 1/2 lbs difference!
