Kabshah, daughter of Ka'b ibn Malik and wife of Ibn AbuQatadah, reported: AbuQatadah visited (me) and I poured out water for him for ablution. A cat came and drank some of it and he tilted the vessel for it until it drank some of it. Kabshah said: He saw me looking at him; he asked me: Are you surprised, my niece? I said: Yes. He then reported the Messenger of Allah ﷺ as saying: It is not unclean; it is one of those (males or females) who go round among you. (Using translation from Abū Dāʾūd 75)   

أَنَّ أَبَا قَتَادَةَ دَخَلَ عَلَيْهَا فَسَكَبَتْ لَهُ وَضُوءًا فَجَاءَتْ هِرَّةٌ تَشْرَبُ مِنْهُ فَأَصْغَى لَهَا أَبُو قَتَادَةَ الْإِنَاءَ حَتَّى شَرِبَتْ قَالَتْ كَبْشَةُ فَرَآنِي أَنْظُرُ فَقَالَ أَتَعْجَبِينَ يَا بِنْتَ أَخِي؟ قُلْتُ نَعَمْ قَالَ إِنَّ رَسُولَ اللَّهِ ﷺ قَالَ «إِنَّهَا لَيْسَتْ بِنَجَسٍ إِنَّمَا هِيَ مِنَ الطَّوَّافِينَ عَلَيْكُمْ وَالطَّوَّافَاتِ»
