My young cat(4montgs old) had extra saliva after eating.Went him to vet,who said that he has an infection in mouth and gums.He gave antibioticsThe worrying thing he said, is that some cats have the above symptoms when they inherit from mother autoimmune diseases like leukymia and AIDS...blood test will clear this out...Also said that if wont get better his teeth must be taken off!!!!!
