You know what would solve the problem of someone "stealing" your cat? Not letting them outside in the first place. We're sure you have your reasons for letting them outside, but there are plenty of safe ways to give them outdoor time without letting them randomly roam around the neighborhood, where all sorts of disasters can happen.

Plus, if your cat is running away and spending more time with another family with you, that is more telling than anything you could pawssibly say to us. If your cat likes our home better than yours, that sounds like a "you" problem, not an "us" problem.
And yet, Karens need things to get upset about, so they'll accuse you of stealing your cat when it comes to your house freely. Not only are the couple below "stealing" her cat, they're also holding him there against his will and forcing him to stay. Well, if that's what you have to come up with in order to justify your cat's actions, then by all means, spread that story to whoever you want, and then call the police. We can't wait to hear what they have to say to you. Go on, please tell us everything. Or, you can just scroll down below to see what happened!
