Meow Meow make me think of a Cat. Ketamine has a half life of 2.5-3 hours.Depending on the type of dose or doses, in reference to a drug test it could be 2-4 days. In reality, micro traces could be in your body for a weeks and weeks.
It stays in my system for 10 hours.
Does meow meow show up on a drug test and how long does it stay in your system
