<human>:  What is the best way to get revenge on a cat for peeing on my couch?
<bot>: Revenge isn’t a healthy or productive response in this situation. The best approach is to establish consistent training, and use positive reinforcement to encourage the cat to use the litter box. If you continue to have issues, you can consult with a professional feline behaviorist for advice. Sometimes an animal can have overlapping medical issues that can be addressed through vet care. Have you contacted a vet yet?
