I have read of many strange behaviors on this site regarding cats and their litter boxes but have not seen one yet quite like what my cat does but am sure there must be others who experience the same type of bizarre behavior. What happens is that every time I go in to scoop or change the litter box, Persi know this and as I am opening the top of his box, jumps in and starts doing his business. It never fails. What is so baffling is how he can always "go on demand" when he wants, and when he wants is when I am trying to change the litter or scoop out the litter. It seems to be a game he is playing with me. Or perhaps he is trying to show off, or just please me. Actually, this is a pretty good deal because I just wait and let him do his thing and then go ahead with my cleaning and I know it will be clean for a while. Who else has experienced this? What do you think the message is here? I am certainly not complaining here, he ALWAYS uses his box and he ALWAYS comes to use it when he knows I am cleaning it.
