TOADS forever!
You don't have to go out with it in the rain, they eat vermine,don't sleep in your bed and don't stink and bark...
No pain whit teeth and claws,they don't piss in the corner of your apartment,don't eat expensive food and don't need a big place.
Edit; Cats are paranoid and, or, schizophrenic and dogs become depressed. Toads are just greedy and argumentative...(in my opinion)
