These are my grandcats, my son and his wife’s cats.
I immediately took your first sentence to mean exactly what you intended.
But then I took “grandcats” to mean the children of your cats.
That seems like a likely use of it.
“HI DAD!!! Let me show you around my new house! So this is the living room, and over here—”
“Yeah yeah yeah, good job. You bought a house. Where are the cats?”
“Uhhh…upstairs I think?”
“Great. Let me know when dinners ready. I’ll be spending time with my loved ones.”
“…okay…dad…”
But just LOOK AT THEM!
Between the picture and your comment that was a double win.
What do you really mean though?
That’s a really great shot of two cats! It looks like they’re posing for the photo. They’re super cute too!
We enjoy and spoil our grandcats more than our own children.
Cats are people!
Humans suck, though.
