Fact: interspecies cuteness is extra cute:

Any article with the words "kittens" and "snuggle" is pretty much a Sunday Cute lock:

Summer has shown remarkable patience with the frisky five-week-old kittens, and lets them snuggle close to her. "I brought Summer inside on bonfire night because I was worried about her being scared by fireworks," Melanie said. "I did wonder how she would get on with the kittens tearing around the house, but she has been really great. "I think they think she's their mum. She's a big, fat rabbit and she just sits there quite happily and lets them climb all over her. It is lovely to see them all together."

The problem, of course, is that these things are genetically programmed to grow into plotting, untrustworthy beasts. But such such are the harsh realities of nature:

So enjoy the cuteness while it lasts. As soon as they grow claws the plot rapidly shifts from "aww" to "dark Shakespearean tragedy of betrayal and loss."
