I have long suspected that many cat species are more social than we think -not just in lion prides and cheetah male coalitions. Many other cats can form strong bonds to human carers which persist into adulthood, a capacity that suggests they may form bonds to conspecifics too. There is also the fact that being born in litters whose members play and interact for a long period, they are necessarily social when young, so that even if they are solitary as adults there is the potential for sociality to evolve. Last week there was a documentary on pumas on BBC2 (Natural World, 8pm Tuesday 24 June) where it was shown that at least this species is less solitary than we had believed. It was thought they came together only to make love or war but this was not so. I suspect that the leopard and especially the jaguar may be the most truly solitary - for keepers tell me that these, especially the jaguar, are the most dangerous and least trustworthy. This is because their feelings and intentions cannot be read from facial expression or body language. If in other cats they can be, this suggests sociality because readable body-language is there for a purpose - to communicate with others. And even the leopard may not be quite asocial - they are trainable and I was astonished last year to see the pair at Twycross feed together without squabbling! Many cats otherwise happy with company must be separated at feeding time.
