@JKTV The difference really is apparent with adopted strays vs bred kittens. I rescued my cat off the street and he's very picky with who he trusts and is extremely food motivated, while my cousin's Persians are the exact opposite. Mind you, my cat was pretty young when I took him in (two to three months) but he still picked up those habits that have stayed with him years later.
@Sarsak No, it's shown in a previous chapter. Only one kitten died. Other than Hachi, the other two of the four smaller kittens got adopted together by a family at a park.
@Sarsak No, two of them got picked up by a family in the park. Haru went to "pick them up" when the bird attacked and she was saved by Tora-nee-san. Then it was only 3, we got the bit with the old lady feeding all the strays and so on. Page 18 ch 16.2 onwards.
