Here are the words of Vivekananda's teacher, Ramakrishna. Ramakrishna is talking to his disciples, recalling an event from his own life. His speech was written down by a disciple on December 16, 1883.
The Divine Mother revealed to me...that everything was full of consciousness...I saw everything inside ... [the temple] soaked as it were in Bliss...[Ramakrishna then did the scandalous: he fed an offering left for a deity, to a cat] The manager of the temple garden wrote to Mathur Babu that I was feeding the cat with the offering intended for the Divine Mother...Mathur Babu wrote back, 'Let him do whatever he likes. You must not say anything to him."
Swami Vivekananda: The Living Vedanta (2006) is where we found this quote, a book by Chaturvedi Badrinath.
