Cleo is the cat I mentioned I got in 2011, yes, so she's 11 years old. I had a black cat called Merlin who, sadly, died in 2020, I had him for 22 years and he was the best friend I ever had. I remember all my pets fondly though and when they're with me I treat them like family members, like I would my children if I had any.
Having a pet makes me a happier man on a daily basis and I think that's a good thing. Maybe you will find out for yourself someday; I hope so.
