Infection control doesn't work like that. Anything that touches the cat's litter or butt might be infected. I.e. you'd have to keep the cat off your furniture, especially eating or food preparation areas -- every time. You'd have to not ever put your face on something that the cat might have snuggled against, or walked on. It's just not feasible.
