My first cat was a very old stray when he adopted me. I was a total innocent, previously only having dogs.
On the first night he came up onto the bed to sleep, I was lying in a very uncomfortable position all night because I was afraid to upset him.
It didn't take long for me to realise who was in charge.
I am glad that Toby has settled, once Princess Merlin died Frankie was a totally different cat. He couldn't believe that nobody was going to beat him up and make his life miserable.
