Hi! My very first squirrel...I’ve had Scarlet the Red Squirrel for just over 4 weeks now. Her eyes opened after the second week so I’m guessing her to be about 7ish weeks now. She was fed the Esbilac powder the whole time and is now at 4 times a day. She has access to Oxbow baby rat/mouse pellets at all times (I assume these are what people refer to as blocks?) and also last week on the advice of another website I introduced fruits. Then this week I added vegetables and some nuts. She seems healthy, shes active a few times each day, about an hour each time. I’ve started bringing her out on the nicer days in her cage. I have also given her fresh cut branches and pine cones. I do however have questions:

If she’s growing and seemingly fine on the Esbilac should I still take her off due to the alert?
She has very little interest in the Oxbow. Should I take all other solids away until she eats it?
I live on 40 acres of bush in Northern Ontario....we get LOTS of snow and blizzards and -25C is not uncommon. I have a nest box built and the frame of a large cage, just need to add the wire fencing. I intend to soft release and feed her over winter but will she be ok? Will she survive a winter by herself? I feed about a dozen squirrels all winter so I’m hoping by spring she’ll be “squirrel” enough for full release. I don’t know if I can winter her inside...I have 4 dogs and a cat and keeping them separated in my small house is hard. One of the dogs is very interested in her and I know he would go after her if she ever got out.
Thanks!
