He needs to be acknowledged like a person living with you would: say hello to him when you arrive and goodbye when you leave, and introduce visitors to him.

Seriously: introduce visitors to him first thing. This will let him know that a) you know the person and have a happy relationship with them; b) the other person is kind by default; and c) you are still paying attention to him.

Attention

He needs and wants conversation, and will talk back. He needs a lot of conversation to be his best

If he gets adequate play every day, and snuggles in bed at night and in the morning, and brushing once or twice per day, with few stresses, he will absolutely glow with happiness.

Going places

He may be OK traveling in a car. Please research the safest way to situate him, in case there’s a sudden stop.

Harness training him should be achievable, and is strongly suggested if you decide to travel with him.

If you travel with Jonathan, you’ll need to spend a lot of time with him, and make sure there are no other cats or dogs at the destination.

If you are away overnight, it’s best to have someone stay overnight with him if possible. This will be especially important for the first months, as he’ll be a bit insecure.

If you absolutely can’t have someone stay overnight, and he’s settled in and feels safe, it might work to get a pet sitter to come see him late at night and early in the morning.

Training

Make sure he will come to you when you call him, even if he’s far away.
