I took these photos last week in Bodrum, Turkey. A cat and dog (both are stray animals) sleeping together in the same place, very closely. Beautiful.
The traditional belief that cats and dogs are natural enemies is not always true. If appropriately socialized, cats and dogs may have relationships that are not antagonistic, and dogs raised with cats may prefer the presence of cats to other dogs. But unsocialized cats and dogs usually don’t like each other.
There are also some dog breeds that are exceptionally friendly to cats.
