They say dogs and cats are natural enemies. But if you’ve ever owned either, you know that isn’t always the case. In most scenarios, dogs and cats learn to live side by side, even in the same house, in perfect harmony. Well, “perfect” might be stretching it. But they at least learn to live together without more than the occasional spat.

In most houses, cats and dogs essentially ignore one another. As long as they both get plenty of attention and have private spaces, there’s nothing to fight about.

In ideal situations, you’ll even have cats and dogs that love one another. They might cuddle, bathe each other, or romp around the house together. And then there are the animals that have spent so much time together, they start sharing mannerisms.

You’ve probably seen it before: a dog that’s spent its entire life around cats, learning to climb furniture and hide in boxes. It’s not very doglike, but it is adorable. If they’ve been around cats enough, they don’t even know they’re not the same. Just take these 60 dogs as an example. They’re convinced instead of being dogs, they’re cats — and it shows.
