Wow,that is interesting,thank's SCM.
When Chico was a kitten,I actually thought I had a brown cat,he was totally brown.
Would lack of Tyrosine have anything to do with the pancreas(sp?)..
Remember when they were both sick,the vet thought Chico had a pancreas-problem...he is not sick now,eats as normal,lots of energy.
I am going to check the cans for Tyrosine,but they eat a variety of 3 different brands of food.
I will not be able to get to the vet before next Monday,but I think Chico will be ok...no emergency.
