Thank you very much for your help. I am taking a sample of his faeces to the vet on Monday for testing and on Tuesday they are taking a further blood sample to test.
What could liver damage mean in the long term? Is he going to die? Or can the liver repair itself?
I will print out a copy of your reply to take to the vets to request a liver biopsy etc.
I have been treating Max with Milbemax, will this not kill lung worms? Or is it a different kind of lung parasite that could cause the coughing and diarrhoea?
He is being fed Burns dry food, a mix of kitten and adult cat food. he was previously on Hills Kitten pouches. I am loathe to change his food again unless absolutely necessary as I am worried that may be causing the diarrhoea in the first place, although I did mix the Burns food in gradually with the Hills.
I will get hold of probiotics and the other things you mentioned - can they be mixed in with his food or water?
Thanks again.
Karen

Lung parasites can cause cough as well as diarrhoea. Please have your cat's faeces checked ASAP, and subsequently treated.
There are uncommon parasites that can affect the liver, such as liver flukes liver parasites can cause liver damage, and thus elevate the ALT.
Whether or not the cause of the elevated ALT enzyme can be determined it may be a good idea to place your cat on a good probiotic, Silymarin (milk thistle), Choline and Inositol, Alpha-lipoic acid, and SAM-E supplements, to help lower the elevated liver enzyme and provide liver support.
The prescription diet L/D can help with liver disease. The best long term diet for cat's is one that is
I just wanted to add that he is also very windy and they smell awful!
