So many domestic cats so close together saddens me

I have mixed emotions about this video. We don't know where this is or in fact what this is but it must be some kind of shelter somewhere. And some people say that the domestic cat is solitary!! I think that you can see that the domestic cat is no longer essentially solitary because they put up with or adapt to this kind of forced social behaviour where they are crammed together in a small space. But they appear to be safe and cared for which is an improvement on being street cats.

They seem to be getting on pretty well but I would expect there to be some stresses and some fights. They are probably fairly content to be there because the alternative is to be on the street where they wouldn't be looked after. 

Domestic and feral cats accept this kind of unnatural situation if there is a food source. The benefit of the food source outweighs or masks the unnaturalness and unpleasantness (at least potentially) of being so close together. Crammed together actually. It saddens me. It is a symptom of human failure in their relationship with the domestic cat.

They have nowhere to go for a bit of peace and quiet and to claim their own territory. Domestic cats are essentially territorial and, in this situation, they have to put that territorial attitude aside completely despite the fact that it is deeply embedded in their psyche.
