Sorry, didn't mean to offend. I am just curious because it seems very odd to me, just me.
I wasn't offended at your question, I just wondered why you chose "5+".

Many people here have larger homes or apartments. Our apartment is 1000 sq. ft. PLENTY of room for the cats...even more so when they all are in different rooms.

Carole and Soledad,
There are many diseases cats can catch outdoors. We have our cats vaccinated for feline infectious peritonitis (FIP); feline leukemia virus (FeLV) infection; giardia; and herpes virus infection and rabies yearly...

There aren't many things they can catch indoors, which is why a lot of vets don't recommend all those vaccinations every year for indoor cats. They CAN catch fleas or anything infectious that another indoor cat may already have.
