Judging by these photos, cats & kittens have a natural affinity to dogs, so it makes me wonder if terms like ‘fighting like cats and dogs’  are fair.  For certain, Xander does his level best to see beyond skin, fur and even scales (he has a bit of trouble seeing past scales and things that slither). Being a good purrtector, Xander compares what an individual says to what they do as a basis to determine their character, instead of the outside fur, etc.

Perhaps, if we humans learned to do that, there would be fewer wars.
