For cat, you can put enough food to bowl and have someone else wisit a day after to change it.
You can absolutely pull all nighters with cat. The cat will be fine.
Less so with dog if you are single, but walking dog is still incomparable to all the interaction that goes on with kid - even on playground.

Your couch or mattress may be ruined, though, depending on the cat.
