When I pet's energy is down what are some ways to get it up? Picking another pet to be active or logging out?

Your pet's energy will increase by one every hour. So if your pet's energy is 0 right now, it will be back to 10 in ten hours. You can speed it up a couple of ways:

--Energy drinks - These are available in the Premium Shop and restore 5 energy points immediately.

--Sanctuary - This building can be used once per day, and it will restore the energy of one pet to maximum. (Before using Sanctuary, though, you need to use the Sanctuary Blueprint and collect the ingredients to craft the building. That might take some time.)

Check out the FAQ section under Pet Care. There's more information on energy there.
