Siberian kittens & cats in Buchanan, Michigan

This is Larry(1.5-2yrs), I was asked to watch him back in the spring of 25. He was a stray that a friend had found and decided to keep. They needed me to watch him while they found a new place. It was supposed to be only for a couple of months but after 3 they told me to keep him. He's a highly energetic and curious cat. He loves to run around and play. I'm sure if you actually got him comfortable on a harness and leash(I tried but didn't succeed) he'd love the outdoors. He also has a really high prey drive. However since he can be so rambunctious he might be a bit much to handle if you don't have the time or space. Sadly thats gotten to the case with me. I don't have the time or adequate space to make sure that all of his mental/entertainment needs are met. He spends most of his time with our other animals(1 elderly cat and 2 adult/elderly dogs) so he does well enough with them. He's a good nice kitty, I just don't have the time or energy to keep up with him anymore.
