Oh please, cats are perfectly fine indoors if they are raised that way. There are solutions, like building a catio, indoor platforms and so forth. You can even train them for walking on a leash in a park. If there is a will there is a way. But people are lazy and pretend letting cats out is not a problem.

And if you are living in a shoebox yourself, where you regard your own home as a "prison" or a "cage", then you have no business keeping such a pet anyway.

> PS: Australia's problem is about the Feral cats and they are making traps in the wild to poison their skin thanks to some box trap and AI.

Feral AND domestic. There are laws introduced in Australia that mandates cats to be kept indoors for this reason.
