Mine didn’t come with a battery

They don’t come with batteries.

Does it hurt the dog?

No, not my knowledge. It works on small dog. It didn’t really work for large dogs.

Can this be used to train cat behavior?

I don't think cats hear the high frequency noise that this emits - so I would say no. Cats are usually able to be trained the best with treats.

My new dogs barks when i crate her to go to work, disturbing neighbors. can i set this unit to emit a sound to stop my dog from barking when i leave?

Yes you can. It works perfectly and after doing it a few times, your dog will know what is coming if he barks. Just show him your hand. That will do it. I used to have the same problem all the time even inside the house. NOT ANYMORE.
