I just put a ceramic bowl of water out that is too heavy for Sandy to knock over. She will just put her arms on the side and put her head in and drink. No problems so far. As far as nuts go only 2 per day maximum. make sure they eat their 2 henry's blocks per day then healthy veggies and fruit. Then nuts only as a treat after they have eaten their healthy stuff. Make sure they do not fill up on nuts and not eat the healthy stuff.
As far as people asking about the NR status of these squirrels. Chelsea mentioned in her other thread that these squirrels are allowed to be around her cats and now have no fear of cats at all. Even if the tail was fine they are now NR for sure.
I just hope you understand the commitment you have made to these little ones. You now have 2 NR squirrels that will live for 10-15 years. They will chew everything in your house, at least Sandy sure did when I had her in recovering from her injured arm recently. I also hope your job doesn't mind you coming in with scratches all over your hands and arms. I was worried about mine but now Sandy is outside again and is not climbing on me nearly as much which has given me a chance to heal fully.
