Earlier this week, the Amakhosi announced that Katsande (35) had been released by the club following the expiration of his contract in a move that saw the veteran midfielder's 10-year stay at Naturena come to an end.
The Zimbabwe international joined the club from Ajax Cape Town in 2011 and made 326 appearances across all competitions, earning the honour of being the club's most-capped foreign player of all time.
Following confirmation of his departure, Katsande took to social media on Wednesday evening to post a heartfelt farewell message to the club and its supporters.
"It is with a heavy heart that I must leave my beloved Kaizer Chiefs family," he said. "I am honoured and eternally grateful to the chairman of the club, Mr Kaizer Motaung, for granting me the opportunity to represent this great institution over the last decade.
"To the peace-loving fans of Chiefs, I would like to extend my heartfelt gratitude for your support and encouragement over the years. You have consistently been the 12th man lifting our spirits, during the good times and the difficult phases.
"I trust that I represented the badge and brand with the respect and dignity that it deserves. 'Respect the badge in the front and the faithful will forever remember the name at the back.
"I am blessed beyond imagination, having represented my childhood club for over 320 games, lifted four trophies and participated in the Champions League. Kaizer Chiefs is my family and will always be in my heart.
"The journey continues and the next chapter of my life commences. To my wonderful children, thank you for accepting Kaizer Chiefs as an integral part of our lives. Love and Peace. Amakhosi for life - Willard 'Salt and Vinegar' Katsande."
