If you live were it is possible it is so much easier to train dogs and cats if they can spend their first days outside quite a bit. They are were they need to be so there are no accidents.
I have two kittens now and I have put netting in a small area to keep them out but safe so using the ground feels right to them.
I have a puppy I got in winter that I could never train even with papers because she hated the cold snow. Because she had been peeing everywhere she just continued to do so although she used the paper for the other. I had carpet and couldn't have this so I had to get rid of her. I really loved her too so I wish I had gotten her in spring as I know to do with animals.
