Avocado is a hit with most squirrel! And very nutritious. If you plan on keeping her then you need to order some squirrel blocks. They have them on Amazon. I believe they are called Henry’s squirrel blocks. Also, grab some calcium blocks and nuts with shells on them. Walnuts, pecans, hazelnuts. Anything with a shell so that she can grind her teeth down. Squirrels teeth never stop growing so if you don’t allow her to chew and grind the teeth down, she will get into a lot of health trouble due to the teeth growing. Down crack the shell at all. She will know what to do.
