as you can see from the attachments, I didn't use the 'sock' method
described on your site, but rather adapted it by using a cut-up old rib-knit
t-shirt and foam pieces. I also noticed while transporting him to
the vet in a basket that the size and shape of the basket forced him to
lay on his side and use his front legs when turning over, so I used the
basket every day - a sort of 'hobble by basket' technique that seemed to
help strengthen his little legs.
