"The fast, white cats run behind the slow, small mice."

Translation: A gyors, fehér macskák a lassú, kicsi egerek mögött futnak.

[Masabobe]

Kis and szaladnak should be also accepted.

I wrote the word cicak instead of macskak (sorry, I don't have a keyboard for accent marks). Aren't they synonyms?

[Linda38047]

Cica is kitten, hence baby cat

[Linda38047]

Does mögött only mean that the cats are behind the mice? Or could it also have the other meaning of "running after something", i.e. "Chasing"?

[Xenocider]

although it can imply the action of chasing (as well as following) sby, for that you'd use "kerget", "űz" vagy "üldöz" instead.
