That's a problem that I have had, too, when I changed over all of my indoor/outdoor cats, save one, to completely indoor.
Yes. I've discovered that both black, and also pure gray (Russian Blue gray) are difficult to see, especially with only low lights on at night.
Nefertiti is splotched black - very black - and white. So while it does break up her colors, I don't have the hard time seeing her that I do with all-gray (even her leather.) Sluggo.
No, you definitely don't want Mussy out. I have the same fear with my critters, who have lost a lot of vision and/or hearing from old age. Yep, our road, too. Yikes.
I know what you mean. I've had a lot of black dogs for some reason, and they don't all bound up to you. Mine have sometimes become selectively deaf when they have become comfortable somewhere!
I'm glad that you found ways to keep the gate closed. I remember that, it was scary!
And, I hope that Charlie never returns to climbing.
Even in my teens or 20's it was impossible to catch certain dogs, and even for Dh, actually, and he ran a very fast mile in high school, plus had longer legs than me.
Scotties, for example. I chased one down a sidewalk next to a lot of traffic once. She stopped, or I would have never caught her.
Our black lab mix Bruiser, also. She was actually the fastest non-grayhound and related breeds dog that I ever knew. Maybe she had some sight hound in her? No one could catch her when she took off running, but she could catch up to any animal.
Charlie sounds a lot like Bruiser.
Well, let's just hope that nothing else to give you gray hair happens. You've all earned a calm, happy life, with....here it comes for 2020....no drama! We'll have to get you guys a llama!
I saw another cute thing with a llama last month. It showed one, and said: llamaste - (in place of Namaste.) :-)
