VetBed for me too. Bought some huge bits off ebay and cut to size, for plastic bed, crates and the back of the car. We use it during whelping and litter raising too, and bought it specifically because it can be machine washed.
Just watch out for the green backing - it has a tendency to wear off during use, leaving a green dust which when you wash it can coat the washing machine... Don't wash whites straight after washing vetbed!
