Hi I Am Going Up To Choose What Kitten I Want When They Are Ready To Leave Their Mum, The Kitten Will Be 1 week Old When I Go Up And I Need To Know If I CAn Put A Collar On Her (NOT A FLEE COLLAR) PLEASE HELP ME

No, no collar. The kitten might get caught on something and choke to death or hang itself. Plus the kitten's neck will grow and the collar won't. A collar is a death sentence for a cat.

Do you want to be able to identify your kitten each time you see it? And I do hope you aren't planning to take the kitten away from its mother at one week of age. Kittens should stay with mom for at least ten weeks. She teaches them so much in how to be a good cat. If you take the kitten away too soon, you will end up with a terrible pet.
