This bed is comfortable, but it is absolutely not even remotely waterproof. The case is pretty good at delaying liquid from seeping through, but the liner is not waterproof. You have maybe 5-10 minutes tops to get the case off and wipe down the liner before the memory foam is penetrated by urine. That's simply not good enough. Waterproof means it stops water from getting through. This is water resistant at best. Now I have a urine scented block of foam that's too big to fit in the washing machine. Petco really needs to vet their third party brands.
