How do I know if I need to bring my cat to the vet to get pain medication?

If you notice any behavior changes in your kitty cat, you notice that your kitty cat's limping, not jumping, cries when you pet it, is hiding from you, we probably need to at least have an exam to figure out what's going on with your cat, whether it's in pain or has something else going on. It's a good indication to have them looked at.
