Yup, rabbits will chew on just about anything, including fingers ;-)

This is a good lesson for the other farm animals, especially pigs. Pigs will eat anything.

True story - in the UK I worked on a pig farm. One day a concrete block fell off a wall and into a pig pen. I saw it in the morning and went back in the afternoon to pull it out and put it back on the wall.

The pigs had eaten it! And they were eyeing up the next block that looked like it might come down.

Makes you wonder how they stayed in the pen huh? And these were super pigs. If they all got out and started rampaging through the countryside, no house withing about 10 miles would have been safe from being nibbled on.
