Is a cork floor pet friendly/durable?
Sealed cork is definitely durable. My parents' house has cork in the kitchen and the family room which was installed ~25 years ago, and the only place where it's showing some wear is in the spot in the kitchen where my mother drops things regularly and they've shifted the oven and dishwasher in and out for servicing. Knives do stick in it rather than bouncing off, which may affect the permeability of the sealing.
