Can cats make friends with other species? Even humans?

Dear George,
Can cats make friends with animals other than cats? These photos, which were sent to me by the human pets of the late Oscar Snuggles, suggests that they can. Of course the most obvious example of friendship across the species barrier is the feelings we have for our own human pets. But I am told there are cats that make real friendships with dogs and even sometimes with house rabbits (though one would want to ask the house rabbit for his opinion to ensure there is no other motive). What do you think? I am just at the stage of increasing my bond with a human.

Dear Matilda,
Yes, there can be true friendships between the different species. It looks as if that is what is going on here. It's not unusual for animals to bond with a different species, if they were brought up together. The famous racehorse the Darley Arabian had a feline friend, who threw herself on his grave and died from grief. Some of us, if we were brought up by dogs, understand dog language and even groom our canine buddies. Some are even friends with house rabbits, the big ones that would fight back if we attacked them.
We cats will often suckle other animals if we lose our kittens. In Victorian times a popular street performer was a man with A Happy Family, a cage full of animals that would normally fight. The animals grew up together and therefore were bonded from a very early age. You can read about this in a classic Victorian book, London Labour and the London Poor
Personally, I would like to turn the tables. What about an experiment with a larger cage with a family inside which included, a tiger a wolf and a human? I dream of the day when zoos contain humans in cages, and we animals stroll round eating nuts and commenting on them. "Oooh look at that one. He's got a lot of hair. Oooh look at those two! What are they doing?"
And of course, there are our human pets. It's friendship but not an equal relationship with them. As the superior species, we have to take try to train them. The apes, as Wicky Wudhler calls them, don't have the temperament or the intellect to cope unless we take them in hand.You can cuddle up to a deer without a second thought but if you do that too easily with a human, you spoil them. Humans need discipline. Some of them have behaviour problems such as not opening the door for us, refusing to give us food from the table or even pushing us off the kitchen surfaces. But more often or not, their funny little ways can be very endearing at times. A cat's best friend can be its human - but only if it is properly trained.
Yours
George
