i found a fun way to play with your gliders and have them eat a tab of their veggies. i had a really long stalk of asparagus (safe for gliders) and i used it like a cat toy, teasing and tickling. they LOVED it they had so much fun batting around and when they caught it, they tried to kill it.....well eat it. my girl just found half the stalk on her table....chew, shake head, spit, chew, shake head spit......as long as they have fun...is ant that all that matters?
