Yes!
I had a male manx
that was probably just a LITTLE too 'bred'
(meaning he had some kinks in his
skwishy little telephone chord of life)
he did exactly the same thing -
slobbering, raw gums his coat went all dull
(which is really ODD for a bladk cat)
turned out
he was allergic to fish!
Anything with fish product!
THen -
he was also reactive to Science Diet.
He could only eat the 'crap' cat food.
You know - the two dollar for five pound stuff.
FINALLY -
when we got it all cleard up...
the neighbor put out poison for mice.
He started doing it all over again.
And it was because he was catching poisoned mice.
So -
there's three things to check for ya.
