April 1st, eh! They are cuties and you'll be "running" in and out all day to see how they're doing - and the mom will soon start to trust you.

I don't know why you can't view the attachment, but I'll give you the link where I found the image - or just do a search for polistyrene box on Google and click on Images.

At least it's spring now, so probably not cold where you are. They'll survive!

If you do put another box next to this one, the mom will surely check it out, and move them there if she finds it better.

Keep us posted, please!
