7. There Will Be No Mice Bothering You. Ever.

Remember that long-term feud between Tom and Jerry? Your cat will probably have its very own Jerry to chase around, but the good news is you will never have to see it. Unless your cat decides to bring it to you as a gift (they are just that thoughtful).

And hey, you’ll save money on an exterminator.
