Since Buster has had his snip, he has started to mellow a bit more.

Now, Buster has always been a sweet cat, and very loving, but he
always had that look of a world-weary, battle-scarred old tomcat. He
insisted on going outside, and vigorously chased off other cats on his
territory.

Now Buster goes to the door, meowing "meowt!", but usually just stands
at the door and looks around. He once just nodded at another male,
instead of running out to chase him off. When he does go out, Buster
generally hurries back, as if afraid that staying outside is now a
punishment!

But most noticeable, Buster looks years younger. Instead of appearing
to be eight or ten years old, he looks more like five or six.

And he has picked up the agreeable habit of asking for attention when
he feels I have been ignoring him too long (like just now - grin).

I definitely think neutering is agreeing with my sweet grey panther.

Hugs and Purrs,
Mark
