I've lived with cats my entire life. I currently have 4 (all rescues): Miles, 14; Fenway, 13; Charlie, 7; Felix, 4.
They're all great companions.
My biggest struggle right now is "dealing" cats who are getting older. It is not the first time, but it has been some time since I've had older cats. I feel like I'm constantly on guard for any changes.
My kids (son 7, daughter 5) love the cats dearly. They consider our feline friends to be a part of our family (as do I).
I just want to continue to give them the best home possible. It has been challenging at times, but always worth it.
