Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) moved forward towards a cat (that is, he quickly stopped it) which wanted to pass in front of him during prayer.
Tabarani recorded it in al-Mu'jam al-Awsat; its chain contains a narrator, Mandal bin Ali, who is da'if (weak).
