It’s either portals or shitting on the carpet. Your choice.

The dogs have had enough of that cats shit.

Edit: dogs

With enough spell knowledge you can put a ward on your cat’s collar that only lets them open portals in the same dimension. So basically turning your cat into a portal gun with pretty much all the limitations of one like line of sight required for opening these portals.

That’s not a cat, that’s a Flerken

Creating a rough protective circle out of dogs and shoes. Very cat-typical.

Feed me now, or suffer the consequences!
