Bez and Chomsky.
I’ve lived with cats for all my adult life and I have never known two boy cats from different litters be so close. We rescued Chomsky when he was found wandering the streets on his own at only 3 weeks old. Bez had only lived with us for a couple of weeks and was just 10 weeks old himself. It could have been a disaster, but thankfully, it was love at first sight and they were inseparable as kittens.
Now they’re almost 4 years old, so they’re off doing their own thing…but it’s still clear to see that when it comes to talking best friends…Bez and Chomsky are it!!
