Same with my now only black cat 3 years young, always brings home prey like mouses etc as if i'm not a good provider.....
THey just do what is natural, i can't be mad about it, luckily the cat here does not hunt birds, just mouses....
Thoug her food bowl is always full, fresh water 3 times a day, and some cat snacks...
My old main coone never hunted, but hated it to be outside just the backyard to get some sun rays...
Miss her still...
