How can cat owners allow them to jump on their countertops and their beds?

Uh, you can simply wipe down the counter before you make food. And I'm not concerned about the bed, it can't be worse than what you might pick up on your own feet and hands just from living with a cat. As long as you clean regularly it's really not a big deal.

Cats like high places. Ours jump on the counter all the time. We swat them off but don't get the message. The counter gets washed a lot. LOL

Don't care really, cause that's not really how it works. Plus I tract in more germs from my job then a cat could ever do

Why would it be filthy unless you're some kind of germaphobe? I don't own pets anymore but for one things you can rarely get diseases from a cat, and for 2 I dont care if i do anyway. you're harldy "sleeping in feces" any more than you would be from farting in your bed.

But Oral sex is OK?
I'd worry more about the public items other PEOPLE have touched.
