Draya,cats jump because they can
They love keeping an eye on things from high places,makes them feel safe.A kitten will explore and kitchen-counters where usually good stuff is kept,is a favourite place
Personally,I don't think it's a big deal and I do not keep foods unattended on the counter.
When my Vinnie first came to my house,strange things were happening,a cucumber disappeared one day and the culprit was Vinnie
I found the cucumber downstairs,together with a few other things,he had a stash
He's grown up now and realized there is no need to stash food and steals no more
