You do you.

Typically, people thrive better in old age with friends and community. For you, that might be pets instead of people. You might need to hire someone to help care for you and the pets at some point, but otherwise, go for it.

Yeah, I really worry about in old age being alone. But not enough to attempt to make friends.
