Cats are strange creatures and no matter how hard we try to study their behaviour they will always do things that they will break the ground rules that us humans might have established as general rules to explain their behaviour.
One of these 'grey' areas that they seem to be really difficult to undestand why they behave in certain ways is their playing habits.
Also cats can easily adapt to their humans' environment and routine with very little training and effort required from the human part.
My cats will get up when I get up in the morning and they will be willing to play with me or on their own in the middle of the day when we are moving about. They are very prompt on the daily schedules and they have certain times during the day when they do things.
Sheng Chi on the other hand she will wait till Choo Choo has gone to sleep before she goes into playing mode herself usually starting carrying around and playing with her little toy mouse and then moving into paper and other balls which she will hide into the tunnel or paper bag or cardboard box. After her playing she will climb on her box by the patio door and she will wait patiently for me to brush her fur before she have her afternoon snooze.
As for Ripley being the oldest and the one that she can't be asked to do a lot of running and chasing she will be at the top of the staircase around 7 o clock in the evenings waiting for one of us to bring upstairs the feather toy so she can chase it downstairs. This s is the only toy that she likes playing with and of course she also likes finding catnips spots on the carpet so she can roll around or she will just use her catnip cushion.
But what it is really puzzling is the things that they find interesting and want to play with. As a responsible and caring cat 'owner' you do feel obliged to buy them toys that you see either being advertised or you see them on pet shops (like buying gadgets for yourself but instead you feel less selfish by buying gadgets for your cats...).
