Caroline@134:  Wool-eating is very dangerous to your cats, because it
can clog or tear their guts.  I'm pretty sure I've read it also may
be a symptom of a nutrition deficiency.  There are links of possible
helpfulness on Metafilter.  A vet is a good first step, but you may
have to find an animal behaviorist.

A friend of mine had a poodle who repeatedly ate her bedding.  The
friend tried replacing the bedding with an extra-tough mat.  The
poodle still managed to eat it, but died.
