It's time for Jeffrey to go to kitty heaven.

This is the part of sharing your life with critters that sucks. They are so much fun for years and years, then reality rears its ugly head and you have to deal with the end of the line. Sorry to see you have to go with this, but hopefully it's balanced by many good memories. 15 years is a pretty good run.

Couple of fine looking cats, by the way.
