Many times it is surprisingly easy to get a homeless stray as indoor only cat. How come? Easy: they know all the horrors of the outside. Outside isnt freedom for them but fighting for survival. Therefore they are very content to live as indoors pet - and becomes often with time great family pet cats.
But Grandpas "stray" cat had the best of both worlds: all the freedom of the outside and security of a good home.
He will not be happy by simply becoming indoor cat. It can probably be done - but probably not at all automatic by itself.
You must work on it. And you must give him good arguments to convice him indoors is a perfect nice alternative to free joyous roaming outside.
A lot of playthings of course. And:
.f,ex: make a lot of climbing possibilities for him. So he can get up to shelves. It isnt that difficult; some planks here and there... (dont forget to fasten the shelves securely to the walls!)
Make him work to find his food; have food or in any case treats, hidden some! So he must seek and find.
Or make something so him must work some to get the food out. feks simply some dry food in a cardboard box with only a small opening. He must stick in his paws and take them out...
Do you have a balcony? Very popular. Set net-cage around, it will be very good.
Very good if there is another friendly cat to wrestle with, chase with, cuddle and sleep with, and wash. So you dont need to play with him yourselves so much...
