The trouble with those seed-mix type foods is exactly what you said: they pick out what they want (the seeds) and leave the rest. Squirrels have a VERY high calcium requirement--almost 100 times the requirement for people when you consider their small body size. Seeds actually deplete calcium from the body. Also, a diet based on fruit, seeds, and nuts will be severely protein deficient. And that's not even considering all the other vitamins and minerals they need. She may look healthy now, but I can't tell you how many squirrel moms come to TSB saying their squirrel was fine yesterday and now she's having seizures.....many of them die. Please read the "Healthy Diet" located in the Squirrel Nutrition forum. In a "nutshell":

A lot of squirrels won't touch commercial rodent block, but almost all of them love the TSB squirrel blocks.
Good luck, and if you have questions, just ask.
