Mustashio LOVES butternut squash, but didn't care for acorn. Must be the bright orange color!! I usually just take a chunk of raw butternut squash (without the peel) and grate it up for him with a cheese grater. I keep it in a little tupperware container in the fridge and sprinkle some on his greens daily. Squash is a great staple! If you grate up a palm sized block that usually keeps in the fridge for about a week or so. I usually buy one medium sized squash and then cut off chunks and peel them as I need them. One squash usually lasts me about a month. Tashi is very partial to his butternut squash and will even dig around all the other greens to get at the orange goodies! Silly dragon!
