Father throws daughter's kittens in the river

[Catherine]

It is strange to think of you knowing that bridge. 
I wondered why she gave the kittens to her father. Did she know he was homeless?
I wonder what her situation is?

England is serious about animal cruelty. Look how quickly the kittens were rescued.
There are many places that would have taken the kittens.
If he had left them in a box somewhere, they would have been looked after.
He really deliberately chose to kill them.
Any small infraction will get him sent to prison.
I suspect being drunk in public would be enough.
