Hmmm Science Selective, Meadow hay, and lots of veggies, grass and dandelion leaves, especially when Daddy is home! He is soooooo wrapped around their paws, and they know it ;D
It's a fine art........ "here's Dad, I can here his voice, let's run to the front of the cage, look excited to see him, and make cute little noises"
Dad,,, besotted by them, falls for it and opens either the front or the back door, which promotes more excited jumping!
But what he doesn't hear is as soon as he's in the garden they go "SUCKERRRRRRRRRR"
Mind you,,,, i'm no better LMAO
