There's nothing unrealistic about keeping cats indoors. The only people
who ever object are those who think it's "unnatural" in some way.

It may not be 'unrealistic' but it is certainly 'unnatural'.

Ask
your vet -- she'll tell you that it's much healthier for your cat to
stay in. It's hard to catch a disease when you don't come in contact
with it.

Using that reasoning, no human would ever venture outside their own house
for fear of catching cold. You've made all vets sound extremely stupid.
