Roxi, my suggestion to you would be for your girl to get 1-2 Henry's Healthy Blocks per day...the Adult Formula. They are a supplementary rodent block that will give her the calcium she needs to avoid MBD. Unfortunately it's never too late for a squirrel in captivity to develop MBD, and with no natural sunlight (only an OPEN window counts) your girl is at risk. Henry Blocks are yummy to squirrels which makes it easy to get good vitamins & minerals into them.
