Strange situation.
I have (or dont have!) 2 cats. One is old, 15. The other is about 6.
The older moggy cat was very happy at home but a (neutered) wanderer.
I got 2nd cat, a BSH, and once he was neutered he followed his brother out.
The BSH took to the elderly couple at the back of our house. His brother followed suit and they were there constantly.
I tried keeping them in but in summer with kids they would inevitably escape and go straight to the other house.
I imagine a quiet house with 2 older people and roast chicken was preferable to our busy household.
So this has gone on for many years and they basically aren't my cats anymore :(
The older gentleman's wife died so the cats are his only company.
I have 'taken them back' many times. Lots at first but it's always the same. They desperately want to escape to his house.
Thing is. We're moving house.
I don't mind, in principle, him keeping them at all. They're his now really but he is older and I'm worried if something happened to him the cats would be abandoned.
But they will not live as housecats. And if I take them and move they won't stay in the house and will run away.
What do I do? Tell him were moving and offer to take them? Ask if he wants to keep them? But leave out number in case eof emergency?
