Question
Only recently, my 1½ year old females cat have been playing "soccer" with a dry food morsel across the kitchen and then returns to the bowl to eat. Why do they play with their food? Are they bored of the particular type of dry food I'm giving them? Do they need me to play with them more?
Answer
It's just their play/hunt instinct kicking in. The piece of food might have dropped outside the bowl, cat uses a paw to get it free (to take it), then notices "omgosh! it's moving!" and starts to "hunt" the food.
Nothing abnormal here and I wouldn't expect this to be just due to the cat being bored. Especially if the other cat sees the hunt, it will join in, no matter what the original cat is after.
You can always try to play more with cats, but I honestly think that this is just coincidence due to the food ball moving the right moment (for whatever reason and unless this really happens consistently).
