MissingLincs You're looking after 4 cats which you say you "do not love, do not like and do not want", and this is so sad for both you and the cats. You all deserve better! Those cats could be much-loved and treasured by other families, and you could get on with your life.
If you daughter can't/won't take responsibility for them as you state, then she can't complain if you rehome them. Your little granddaughter will soon adjust.
I have had rescue cats all my life and the rescue centres, not just Blue Cross, are well used to people taking cats there who either don't get on with other pets, cause allergies or are not accepted by landlords. You would not have to pretend anything.
You could have many years more of this, and believe me, those little cats will know that they're not loved or wanted, and meanwhile you feel resentful and fed up.
No offence but if I didn't have a lovely adored cat of my own, I would offer to have them as I believe every pet should be in a loving home.
I do hope you find a way out of your dilemma.
