I hope you're taking pictures..
3 out of 4 of our buns can jump very high. Poppy is lazy but can easily jump on the bed when she wants to! Donny and Lola can and have jumped 3ft+ but Leo doesn't jump, (only into his litter tray) or binky, he doesn't know how
Donny, Lola and Poppy have houses and boxes that are about 1ft/ 1.5ft high
so does Leo but he can't do it.
