I have found a few levels where the pets just never seem to turn up. it seems to me like a bit of a money grab. This time I suffered through and kept paying my gold bars. The last time this happened (can't remember which level) I was on a 99 game winning streak and Pet Rescue ended the game saying there were no more options and booted me out. I never even got a chance to pay up for more moves or bombs or whatever. I like this game but I really hate it when there are levels like 1464.
