Drown them!

My wife had a phone call from her mum and dad earlier today, They said, they can't cope as their cat has unexpectedly given birth to 9 kittens.

The wife told me and asked if I would help.

"How can I help?" I asked.

She said to me "get over there and put them in a sack and dump them in the canal"........

I did this and I now feel really guilty

Spoiler:

as I got on really well with her dad!
