ALT (alanine aminotransferase) is a liver enzyme - levels are raised when there is damage to liver cells for any reason. I can't imagine why this would happen in a normal healthy cat, it may well have been an error in the test.

If your cat seems in good health and has no other abnormal results, I'd say it would be OK to go ahead with spaying. But your vet is the best person to advise of course.

I have no idea how any dried food would do anything to reduce ALT levels - that sounds like outrageous marketing hype to me!!
