I have an elderly acquaintance who lined me up as the inheritor of her cat. I'll not give the entire story here...
I was prepared to take it on, reasoning that it couldn't live forever, but I'm distancing myself now: elsewhere, I've explained that she wanted a plan of my house, wanted me to add on a balcony for the moggy, build a catio, etc...
I'm now convinced that if the cat dies, she'll simply buy herself a kitten and I'm not prepared to take that on. (She's had umpteen cats over the years.)
She's now advertising on FB, but claiming that she's lining up a future home for someone else's pet. She ran exactly the same ad with exactly the same details for the cat a year ago. It was supposed to be 7 yrs old then and 7 yrs old now, so goodness knows what age it actually is.
The whole story became increasingly batshit as time went on - it's at the stage that I find it hard to believe myself. When I was supposed to be getting the creature, she insisted that I had to sleep over at her place on an air mattress* in the living room so that it could "bond" with me...Oh, and it would love to play with my hair. Pass.
As I said in my original comment, I'll not take on any responsibility for a living creature again.
