Found to be solvable with moderate lookahead by valerie.

When I got stuck, I saved what I had done so far, then tried repeatedly placing column 19's 2 in various places and solving the puzzle forward until it didn't work, then reverting to my saved version. There was only one spot where it did work.

Is that considered a legitimate way to solve a puzzle? I'm sure there is a more elegant way to figure out the logic than the way I did it. :-S

IDK Brian. Looks like roadkill. 23 hours might not cut it.

Valerie: you can use 2-way logic, to see that the vertical and horizontal clues match up in the upper right corner, to create a zigzaggy line. (2 1 2 1 2) matches up with (3 3), for instance.

That zigzaggy line could come from either the top right corner or the bottom right corner, so 50/50 shot there

I have often wondered why a cat in the same room, same temperature will sometimes look "melted" like the cat in this puzzle, and then other times will be curled up in a tight ball.

Thanks Kristen!

Because, Norma, cats can drive us nuts even in their sleep!

You better believe it Bill. Just last night, my cat, who is quite heavy, moved to where my feet belong when I got up in the middle of the night. He was sound asleep when I returned and refused to budge when I tried to get back in bed.

After initial LL, edge logic on R4. R17-19 are dots, otherwise it makes R3 invalid. LL to finish.

Nice puzzle!
