ANSWER:

There is nothing to state that our Prophet salla Allahu alaihi sa sallam used to love cats! He only once gave it water to drink from a vessel.  

It is not permissible to buy and sell cats, but no problem in taking care of them.

Did Muhammed Sal’lalaahu Alaihi Wasallam love cat..? Can we buy cat and any incident related to cat by Muhammed Sal’lalaahu Alaihi Wasallam
