Translation:Even my cat likes to launch this application!
...or you use "to" and the basic form of the verb. Are you suggesting the given translation is wrong? It's not.
"likes launching" is of course also correct, so if that is what you wrote and it was deemed incorrect (and there wasn't anything else wrong with your sentence), please report it and it will eventually get added as a correct answer.
Yes it helps more than normal. When learning a language you need to be prepared to lear to understand a fable. Otherwise you'd not be able to understand why a tortoise and a hare are running such an uneven race. Or why a magic mirror can tell who's the most beautiful lady.
If you study a language you'dlllp understand a story in which the characters are talking animals or things.
