They are very much all unique individuals, just like humans.
I have a cat I love very much. Rescued her when someone threw the litter she came from out in the trash. Raised her from about 3 days old. She’s 10 now and follows me around like a puppy. My brother and I have been rooming the last two years to save money. The cat still doesn’t trust him and runs from him about 9 times out of 10. She will hiss at me once in awhile. She doesn’t like me to pick her up, but she will jump in my lap. Go figure. Cats rule, but in their own version of the world,lol.
