Feeding pork to cats

The tins of cat food include pork. Is it permissible to buy them for cats?

Praise be to Allah, and blessings and peace be upon the Messenger of Allah:

We put this question to Shaykh Muhammad ibn Saalih al-‘Uthaymeen, may Allaah preserve him, who answered as follows:

If you buy the tins, then it is not permissible, because it is not permissible to pay for pork and buy it. But if a person finds it by chance and feeds it to his cat, then there is nothing wrong with that.

And Allah knows best.
