Yoggies are very hit and miss around here.
They like the Vanilla Yogurt chips(that have yogurt powder in them),I order them from Nuts.com when I order pine nuts and pumpkins seeds for them.
They are not the same as the white baking chips. None of mine like those at all.
The Yoggies brand treats in the small pet section also are not liked here except for the "Cheese' flavored ones...all 7 love those(they are cheaper at walmart($2.24 a bag compared to $4.49 at Petsmart and Petco). There are some mixed berry flavored and cherry vanilla flavored ones...none like them at all.
I have the mini vanilla yoggie chips from suncoast that they all like, the mini cherry flavored and peanut butter flavored chips from Newby's Glider Nook...only one cage of gliders like those...the others won't touch them.
You can ask if they ship on ice packs(some vendors do),if you want to ensure they won't melt into a big glob when they ship to you. Some vendors won't ship them at all in the summer months.
