Dear Secret Buddy,
If you want to get Henri a collar, go for it!
It appears his has gone missing, I have searched the entire house and my car for it but can't find the darn thing. I think the little stinker hid it, probably buried it in the backyard. Oh well, it wasn't a very nice one anyway, I bought it for $3 at Walmart.
So, if you want to get him a collar then go ahead, it would be appreciated (by me, not sure how much Henri would like it
).
