Cats aren’t pack animals, but they do socialise with humans, other cats, and other animals. They don’t all have the same personality and some will tend to be more social than others.

In general, I would say that if a cat normally has human company most of the day (e.g. a human who doesn’t work or works from home), human company can be enough (circumstances vary). But in general, if the human(s) are gone a lot of the time then it can be lonely for a single cat. In that case it’s worth getting them a four-footed companion.

We had a cat who preferred having us to herself rather than sharing us with another cat. But we could see that she got lonely when we had to leave her by herself, so it seemed better that she had a companion cat even if she didn’t want a friend.

At our current house, the yard is open and various neighbourhood cats will come into the space. Our boy accepts two of them. I don’t know if they are “friends”, but they come to visit and he’s chill with them. Any other cat coming into the yard, he tries to fight off. Some fascinating cat politics going on.

I have actually gotten shipping notifications from Amazon when I placed the order on eBay.

Several times I have purchased an item on email only to have it arrive from Amazon. The sellers were using both sites and there was no way to tell from the eBay listings. Big sad.
