hi This is my first post to a forum. We have adopted a lovely 1 yr. old rabbit named Albus last May. He had a great summer playing outside (for the first time) at our cottage as well as in his run here in the city. He's enjoying playing inside these past few months - it's winter in Toronto. But, we're wondering what temp is it ok for him to go outside again. I don't want him to get chilled and sick. We don't know much about where he 'came from', so I don't know exactly what kind of rabbit he is, other than he doesn't seem to be a dwarf bunny. The vet said he weighed about 3 lbs.
