It just crossed my mind that the PEX tubes might be attacked by unexpected
inner wall/floor visitors (mice, rats, ...). Is there a preferred method of
protecting the PEX tubing from animal attacks in more exposed areas like
crawl-space?
On a slightly different note: how difficult would the PEX tubing
repair\replacement be if the tube is in the exterior walls insulated with
spray foam?

I don't think it is much of an issue. There is nothing good to eat in pex
and if the walls are filed with spray foam, that is going to give a measure
of protection. Rats would be capable of chewing through copper also.
