Oh that is cute & clever. Really like the 2nd photo. I have the problem of trying to unteach my pets tricks that I never taught them.
The pooch, who is from the RSPCA, used to dance upright on her hind legs whenever I was trying to put down a plate of treats. After knocking over & breaking 2 ceramic vases, I re-taught her to sit on command instead or no treats.
My piggy boys stand upright trying to grab the vegie bowls as I am trying to set them down. Then one day Hazelnut decided to fling himself out the door at the vegie bowl the minute I opened it. Managed to drop the bowls & catch him before he went flying to the ground (their cage is on a table). Now I lower the bowls from the top opening lid. But they jump around upright knocking each other over trying to reach the bowls & a few times Peanut Butter has knocked his snout against the ceramic bowl. I m at my wits end trying to figure out a safe way to give them their vegies in the cage!
