For his birthday, I bought Orion a leash. I never thought I would be that person. But...we have a few cat walkers in my neighborhood which got me started on the idea. And, well, fuck the stereotypes - I think it would really fun and that Orion would love it. Of course, cats don't take to leashes the way dogs do - so its a process to actually get him outside.
Step one - get him used to the harness.
So far I am enjoying this step far more than he is. Every time I put it on him, he lolls around the house, flopping and rolling over until he finally tuckers himself out.
