How many is too many?? cats that is!?

Hi there. I say you can never have enough cats. I love cats I have 5 of them. 1 female and 4 males if I could afford to have more I would. They are loving animals and they know when you are feeling sad. So don't listen to the person who told you to take them to the RSPCA. Sounds like you have a big enough property for them to run around in and I know the feeling of the cats having the run of the house. I have 4 cat posts, 4 beds, heaps of toys through the house and a huge tunnel in the hallway. They are my babies and just love giving them things to do. The ages are 17, 16, 11, 9 and 2 years old never a dull moment in my house. I wish you all the best with you cats.
