Chris took Trent out and plonked him smack in the middle of the catnip patch for a treat.
Trent enjoyed it, but it overloaded his system. I guess it was all too overwhelming--a little sprig from the patch is more than sufficient.
He threw up later. Like a kid at the amusement park.
Lesson learned: 12-year-old cats can't handle too much excitement, even in plant form.
