While the official death toll may still be stuck at "small numbers", at
least one major veterinary chain has reported kidney failure in cats
during the time in question as showing a jump to 30% over the expected
This would indicate a *lot* of dead and severely ill cats. (Kidney
failure in old cats is fairly common, so the background level would not
be insignificant.) The official number takes a long time to update,
partly because they have to test a lot of carcasses.

Cats might be unusually sensitive to melamine; they react differently
from most mammals to a number of things. If I have this right, part of
the problem in determining whether the melamine actually caused the
problem or not is that nobody ever tested this for toxicity in cats; as
nobody expected it to end up in cat food.
Of course, this possibility doesn't prove that it was the melamine that
caused the problem. But it's risky to make assumptions between species.
