Training your cat to come when called is achievable by using sounds they find enticing, such as the sound of food packaging. The opening of a refrigerator or a can of wet food, for example, can attract your cat and eventually establish a conditioned response.

Establishing a Verbal Cue for Recall
Begin by selecting a clear and consistent verbal cue, such as "Kitty, come" or "Here, kitty". You can also use a clicker if your cat responds well to it. The key is to start with a chosen command before you introduce the lure.
Using Enticing Sounds as a Lure
Use sounds that are inherently attractive to your cat, such as the distinct sound of a can being opened. However, ensure the verbal cue is delivered before the sound and not simultaneously. The sound should always follow your vocal command. Avoid letting your cat hear the can opening first, and only then, your command.
Basic Training: Linking the Command to a Location
Start by training your cat to associate the verbal cue with a specific location, usually their feeding area. Each time you use the command, guide your cat to the designated spot, such as the kitchen or their food bowl.
Advanced Training: Extending Recall to Different Locations
Once your cat consistently comes to the usual location when called, move to other rooms. Use your chosen 'come' command, and when your cat finds you, immediately offer a tasty treat or food reward. Don't forget to pet and praise your cat simultaneously. Positive reinforcement is vital.
Consistency and Continuous Reward
Regardless of whether your cat has mastered the 'come' command, do not underestimate the effort it takes. Reward, encourage, and praise your cat each time they successfully respond to the command. This will help reinforce the behavior, ensuring a reliable recall every time. Consistency is key in cat training.
