Sometimes, baby wolf and baby ocelot (tamed or not) won't follow water stream.

Instead, they stay in place, that will make them drown after a while.

Step to reproduce:
►Place water.
►Spawn a lot of baby wolf (or baby ocelot, tamed or not).
►Half of them (or less) won't follow the water stream.

It should be fixed, since this is a very important bug.
