What happens to the pets on Sims 2 Bon Voyage when the family goes on holiday?

I want my family to go on holiday but i don't know what will happen to the pets, will they die or will they live?|||you are suppose to hire a nanny because other wise the animal control officers might take your pet, or one person might not be able to go on the trip. It is like when you leave a kids alone...you can't...hope I helped!|||of coarse theyll live...its like they freeze where they are when you go somewhere...
