Norwegian Forest Cat kittens & cats in Saskatchewan

Oliver was a friends cat that I took in. He is around 6 years old. Oliver is a silly little boy. I would like Oliver and my other cat Jarvis to be adopted together. They have lived together their whole lives and I do not want to split them up. Oliver and Jarvis are both indoor cats, they have never been outside, or even tried to go outside. The future owner would need to keep them inside (they should not roam outside by themselves). I have never tried walking them. I feed them a mixture of wet and dry food, and add water to the food, otherwise Oliver tends to drink too little water. He loves attention, and needs an owner that is there to keep him company. He loves pets, and hanging out in the living room. I am nervous to rehome Oliver because when I moved last year, he did not handle it well. I would assume it will take a while for him to get used to his new home, and he will need someone with patience to make sure it is a seamless transition.
