Ishaq bin 'Abdullah bin Abi Talha إسحاق بن عبد الله بن أبي طلحة · The Book of Purification

"By Allah, I do not know what I should do with these Karais (toilets). The Messenger of Allah (ﷺ) said: 'When any one of you goes to defecate or urinate, let him not face toward the Qiblah, nor turn his back towards it."

"I poured some water from him for Wudu', and a cat came and drank from it, so he tilted the vessel for it to drink." Kabshah said: "He saw me looking at him and said: 'Are you surprised, O daughter of my brother?' I said: 'Yes.' He said: 'The Messenger of Allah (ﷺ) said: They are not impure, rather they are among the males and females (animals) who go around among you."

"I saw the Messenger of Allah (ﷺ) when the time for 'Asr prayer had come. The people looked for (water for) Wudu' but they could not find any. Then some (water for) Wudu' was brought to the Messenger of Allah (ﷺ). He put his hand in that vessel and told the poeple to perform Wudu', and I saw water springing from beneath his fingers, until they had all performed Wudu'."
