I think I've mentioned our neighbor's cat, Tiki, before. Tiki is a huge bully. She absolutely terrorizes our cats. I can't let Patchouli out in the yard unless I am there to watch over her. Even Coco has to constantly keep an eye out for her.
Not only does she terrorize the cats, she gets on our back porch and sprays our grill cover. She goes on the front porch and sprays our front door and shreds our welcome mat!
I keep a Super Soaker Water gun by the basement door and I use it to chase her off. She is not the least bit afraid of me if I don't have that big water gun!
Even when I'm shooting her with water, she'll pause at the end of our yard and spray one of our bushes before dashing away!
I've also watched her circle around as soon as I go in and come right back over!
Oh well, what can you do?
I used Topaz Labs for my artsy photo of Coco keeping a watchful eye on Tiki.
