CBS says The Price Is Right is planning a milestone birthday celebration for former host Bob Barker.

Barker will celebrate his 90th birthday with an appearance on the game show in December, the network said Tuesday. He retired as host in 2007 after 35 years with The Price Is Right.

The show will also pay tribute to Barker’s longtime animal activism by featuring pet adoptions during the week of Dec. 9-13.

Barker will be on The Price Is Right on his birthday, Dec. 12, and will present a special showcase to mark the occasion, CBS said.

The Price Is Right, with host Drew Carey, airs weekdays at 11 a.m. ET on CBS.
