An idiom or a figure of speech that conceals where you are truly going and what you are really going to do. In all honesty, you are sending the message that you are heading for the toilet to lay waste in. This phrase is derived from a much similar phrase, does a bear crap in the woods?, which is a question that is posed after someone states the obvious.

See Going to see a man about a dog and Going to see a man about a horse for similar phrases.
"I'll be right back. I'm going to see a man about a bear in the woods."

Get the i gotta go see a man about a dog mug.
A reference to a classic book published in 1937. In the book one of the main characters, "Lennie" murders a women by mistake because he had a mental disorder and she was trying to seduce him into doing sexual acts with her... its alot to explain.

tldr: She told Lennie to grab her hair, he grabbed too tight, she screamed to let go, he paniced and killed her. So Lennies best friend, (another main character) George took Lennie to go see the rabbits i a forest by a body of water so Lennie could be in a happy place before George shot him in the back of the head because he was worried Lennie would panic and kill another person and get in even more trouble.

To "Go See The Rabbits" yourself or to take someone else to "Go See The Rabbits" could be subtly refering to suicide, putting down a pet, or murder.
Example #1:

Random Guy: "Life hasnt been going too well... maybe i should go see the rabbits"

Example #2 (i wouldn't do this... sounds kinda fucked up):

"Maybe i should go take (pet name) to go see the rabbits. he/she's getting very sick/old"

Example #3:

"If you dont shut up im gonna go take you to see the rabbits!"
