I know dogs need to be placed in a kennel while visiting DVC properties. Does the same hold true for cats and birds (small caged variety) or are they permitted in the units?
We have used the facility at Fort Wilderness and it is very good. My wife saw several cats being kept at this facility. The DVC documents have strict rules on no pets in several places in the documents. The only exception would be service animals as required by the ADA.
The only place I know pets are allowed is in your own camping unit while staying at Ft. Wilderness. Even then, you must be camping in one of the "Pet Loops" that are specific for that purpose. And as expected, pets must be on a lease at all times.
