Testing if Whether Dogs or Cats are more Playful

Abstract :

I've always wondered whether cats or dogs are more playful so I decided to test it. First I went to the animal shelter on the weekends and when I was free,and I timed how long they were playing with me. When they got distracted I would stop the timer. It turned out that the cats were more interested and playful crazy right.So in conclusion the cats were more interested in playing and being around me.Further studies i could do is if i give them treats do they stay longer?
