I am wanting to adopt a cat from one of our local shelters, and I have a few "favorites" picked out. One is an 8 yo male Ragdoll/SImaese mix, and the other is a 2 yo female Manx mix. I've been researching everything I can think of online before I decide to adopt one, but after doing some research, I'm a little concerned about adopting an older male. What do you guys consider a "senior"? Do male cats actually have more health related issues than female cats, or am I just being paranoid? At what age do "senior" health problems typically start showing up? Should I be concerned about his diet prior to coming to the shelter? Could it eventually cause health problems even if I'm feeding quality wet food? Should I mix wet and dry? I'd appreciate any suggestions. Thanks!
