Use a comfortable cat harness and light leash made for cats to avoid injuries.
Get the Right Gear
Introduce the harness gradually. Let your cat wear it while relaxing to get accustomed to it.
Take it Slow
Start with 5-10 minute leash sessions indoors and slowly build up duration over weeks.
Do Short Sessions
Reward wanted behavior with treats and limit pulling or stopping with gentle leash tugs.
Positive Reinforcement
Accept setbacks gracefully. Stay calm and keep sessions relaxed, positive and comfortable.
Be Patient
As your cat improves, slowly add more distractions indoors like toys and sounds.
Distractions
Much later, move to a safe, enclosed outdoor area to generalize the skills.
