Hi Frank. Awsome . A black rats are totally awsome. They can sense your persona. I love them. Mine are very tame in my yard. I just pick them up. I have never been bitten by Frank or Freda. They had babies last year I baby black rats every where even in my basement. . They all get moved to my woodpile. Frank k is big enough I drape him across my shoulder and he just crawls off and over my neck an goes into my wood pile. 😊😊 God bless. Pennsylvania buddy Jeff. 😊😊
