I agree with Horsey. Call rehab or take care of it yourself, entirely up to you. When I was very young, my family raised an entire litter of baby squirrels. They were fine until they got big enough to be destructive in the house. The possums we also raised we didn't get to keep very long. They wanted to "cling" to my mom all the time and she wasn't liking it.
Which would you prefer Red? Baby squirrels dropping in your lap or the three spiders I had in our house yesterday? They are so desperate for water they are marching in and straight to the dogs water bowl.
