I don't know, I keep the furball out whenever I can [and there's a swii in the background] but he doesn't seem to dislike the Pokeball and in the case of your Pokemon... well, I bet they would prefer being put into Pokeballs over slow and painful death of dehydration... I wonder how long would they be able to survive without water.
