How long to bearded dragons live for?

Also, how do they do with cats?

Thinking ahead to when Tigger's no longer here (will also depend how easy it would be round here to get stuff they need)

Also, it would depend on Willow - whether she would allow one in the house without being like "how very DARE that creature come into MY HOUSE"

cause she can be a madam when other animals come into the house (other cats, insects, you name it she gets angry if it comes in)

I have known her to anger yowl at a spider that got into the house - as though i can control spider behaviour .......
