Max in particular is too a plant-chewer. He seems to favour the spider plant which is probably out of all our house plants is the most likened to a cat toy i.e. its long with tufty bits and is quite springily-responsive to a batting cat paw.

He loves to have a good chew away at that but is not interested in any of the other plants really. AND he has daily access to the garden and the multitude of plants we have there - have never seen him show any such interest in those.

I would agree with the others that its more likely to be a playful fascination rather than any degree of malnourishment. i certainly have no concerns about his appetite, eating habits and physical condition as a result.
