Shadow's friend

Shadow has a friend...she's always going out into the woods with it.It's a calico cat.She's fixed...but, it just annoys me.Should I stop this.if so, how?

Shadow, Bugs, Seth, me(Jenna), and Shadow's new friend.

Well, calico cats are almost always female, so that shouldn't be a problem anyway. But of course, all outdoor cats are subject to various kinds of diseases and parasites, and I assume that's why you're concerned about Shadow spending time with this or ANY other cat. Am I correct?

The only way I know to keep her from associating with other cats is to make Shadow an indoor kitty -- which would be much safer for her, anyway!

I wonder how many birds they manage to catch out there every day?
