I'm sure they do love you....in their own bunny way. You might try I'd try sitting on the floor with them more often and talking to them while watching tv or reading. I just now saw you email from March on Tunnels! My apologies.

The answer is--go to Lowe's or Home Depot or someplace that sells home improvement stuff and buy a concrete form...they use them to set mail box posts or deck footings. They come in different sizes so even BIG buns can get through them. Bunny Bytes has a great tunnel made of willow, which they can chew on and Busy Bunny has a triangular tunnel that's real good too.
The only problem with the concrete form is that it's round so it rolls. I ended up putting theirs between the wall and then put something heavy in front of it so it wouldn't roll why they are in there. Hope this helps.
