my 2 precious kitty kat brothers?

Question

I have 2 brother cats and one of them is really sick i went to the vet and found out what is wrong but do you think the other cat knows that his brother is ill... bc hes been licking him and grooming him , and it seems like he checks up on him. What is that ?/

Answer 1

Yeah, he knows he is sick, that is why he is grooming him, licking him, I hope the one cat gets better because his brother will be so lonely if he dies.
