Ah ok, the coat looked similar and they seem bonded. Was he not pissed off with the introduction?
Good on you for getting rescues. All mine have been.
He spent three days hissing at them, started relaxing a bit and then decided they needed cleaning and next thing we knew, they’re all snuggling together. Today was the first day that he’s settled down to lie with them.
He has always been affectionate, to other cats, and got on well with the old girl who I had for 19 years before she shuffled off a couple of months ago. He’s a bit less cuddly with people, but he’s coming around slowly.
