I calculated this morning that of the six cats we’ve had here at the Gulch – all now dead – only three died in such a way as to leave a body, only two died non-violently, and only one died of old age. And that one spent her last several years inside a townie house. Conclusion: The desert isn’t a good place to be a cat person. Or a cat, for that matter.
However the Secret Lair is still equipped with a cat door, and LB does get use from it. I just set it so that it can open outward but not inward, and it’s just big enough that LB can’t get his head stuck.
