@Tima87,
Tima87,
Please DO NOT declaw your cats. It is mutilation . It renders the cat defenseless , can't protect itself if attacked, can't climb to escape. Declawing also affects a cat's gait. Keep your cats' nails clipped; you may need a person to help, one to hold the cat, one to clip nails. Use a special clipper or scissors. I use a cat nail scissor that has rounded tips and an inner hole that allows me to position the claw. If your cats have black claws, and you can't see the vein, you might want to let a groomer or a vet handle the clipping. Some cats are amiable to having their nails clipped, others not so much....understatement.
Since the 70's I've had six cats. Two went to the vet for nail clipping, the others were OK with my doing their nails.
I definitely recommend neutering, especially if you have a male and a female. Don't wait, even if they are the same sex, there are other cats around who will get to your cats.
Enjoy your cats, and give them a good home. You've received excellent advice from others on this post. I hope you are becoming more accustomed to cats in your home, in your life.
