About 3 weeks ago i adopted my lop mix, Geno from a humane society. Since then he has become more comfortable around me, however he will not leave him cage. i leave the front part of his cage open for him at all times but i am certain he doesn't leave. I was maybe thinking that he doesn't want to hop over the front part of his cage so i was contemplating building a ramp for him, but the cage is only 6 inches off the ground. I am just curious about opinions on this. If anybody thinks i should build a ramp could you maybe give suggestions on how to do it? Also, i think its important to note that my floors are hardwood, i have put him on the floor in the room, he walks around for a short period of time and then goes back to his cage. could i possibly be because he does not have enough traction and doesn't feel comfortable walking on hardwood? Should i start by putting a rug down maybe? Thank you!
