I suppose it is pretty obvious what this Bengal cat mother is saying to her offspring. It will be the same sort of words and sounds that a human uses to reassure her young child.
It must be about providing reassurances to her kittens. The mother makes a trilling sound the kitten makes a faint kittenish meow.
The mother adds to the reassurance she provides by making physical contact as well. Nuzzling her kitten and touching him with her paw.
There is a great similarity with human behaviour. People who don’t like cats should recognise that. It may stop them mistreating cats.
“Are you alright?”
Mother makes baby noises.
“I want to get out of here and explore”
“Yes, dear” (while ignoring the request)
“I wanna get out”
Mother ignores request but is happy about the safety and welfare of her kittens.
