Cooper is one determined feline. Found another, different collar, with tags reading "Cooper," in my front yard this morning. Apparently my cat is not scary enough to run him off and is just enticing enough to lure him back. If you want Cooper's second collar, email me and let me know. If I find anymore, I am just pitching them. And if I catch Cooper peeing on my porch again, he's going to have bigger problems than lost collars.
