A difficult relationship

I’ve lived with him for four years now and our relationship has hit a desperately rocky phase.
Oh, he has his good points. He’s good looking, cool, suave and sophisticated - I’m the envy of many of my friends, in fact.
But sometimes his behaviour is so cruel and despicable towards me, the kids, our neighbours - I just can’t bear the torment any more.
I think the time has finally come to admit it.
I hate my cat.
Honestly, he’s a complete git and I’m starting to wonder what is the point of him living in the Bad Mutha household at all.
He never gives any of us any affection - slinking away if you so much as try to give him a friendly pat.
If he deigns to come and join us as we relax in the living room in the evening, he won’t sit on my knee like cats are supposed to. He’ll trot off on his own to some remote corner, then start randomly clawing at the furniture or carpet until he annoys us so much we have to chuck him outside.
We had to withdraw his cat flap privileges several months ago because he kept bringing mice into the house.
Live mice.
Who then escaped and set up home in various other parts of our ground floor. One managed to live quite happily inside the sub woofer speaker underneath the telly for quite some weeks. Which was odd.
So now the cat is only allowed free access to the conservatory.
And that’s where he mainly prefers to stay now, the antisocial little lowlife.
The thing is, DD2, who is 17 months absolutely adores him.
She screams with delight whenever he comes inside to eat his food and tries to give him a kiss.
One of the first words she uttered was: “Cat!”
He repaid her last night by scratching her face.
Evil little tosser.
So what do I do?
I couldn’t bring myself to drop him off at the RSPCA - the guilt would be too much for me.
And much as he deserves throwing in the local pond, animal cruelty just isn’t Bad Mutha’s style.
My only hope is that he wanders off and finds some little old lady to move in with.
Or maybe you know someone who’s looking for a cruel, annoying, unfriendly, unlovable, selfish, not very clever, fairly violent pet to take care of?
Thought not.
