Abu Qatada came in to visit her. She mentioned something to this effect, that she poured out water for him to perform ablution. A cat came and drank from it, and he tilted the vessel for her until she had drunk her fill.Kabsha said, "He saw me watching him and asked, 'Does this surprise you, my niece?'I replied, 'Yes.'He said, 'The Messenger of Allah ﷺ said, "Cats are not impure. They are among those who frequent you, the males and the females alike."'"
أخبرنا قتيبة عن مالك عن إسحق بن عبد الله بن أبي طلحة عن حميدة بنت عبيد بن رفاعة
أن أبا قتادة دخل عليها ثم ذكرت كلمة معناها فسكبت له وضوءا فجاءت هرة فشربت منه فأصغى لها الإناء حتى شربت قالت كبشة فرآني أنظر إليه فقال أتعجبين يا ابنة أخي فقلت نعم قال إن رسول الله ﷺ قال إنها ليست بنجس إنما هي من الطوافين عليكم والطوافات
[Its chain of transmission is sahih. Abu Dawud narrated it in the Book of Purification, Chapter on the Leftover Water of Cats, (75), Tirmidhi (92), and Ibn Majah (368), from the hadith of Malik through this route. It is also in the Muwatta, 1/22, 23 (Yahya's version), and in Sunan al-Kubra (63). Ibn Khuzayma, Ibn Hibban (121), Hakim, Dhahabi, and others graded it sahih.]
