I'd really like to see a bunch of pictures of Maple
from different angles.
From the pic you've posted I don't see any lump
or bump on the spine. But would like to see more.
ir has given you great advice. The legs need to be
worked so blood flow continues. Being able to
poop and pee on his own is very encouraging to
hear.
A splash of heavy whipping cream in his formula
may help.
Where their any visible wounds when you found him??
Are the rear feet(the pads) warm and a little almost
like sticky feeling or do the feel dry???
Sorry tons of questions.
