OK we are the third owners (I think) and she was born Dec 2019
we have had her since midMarch
We have extra strong feliway & she is predominantly an indoor cat - a catio is a possibility
She isn't very happy; she stalks and attacks our feet, she over eats, she is very bite-y - we just had to change her food which made things worse
She isn't play fighting really although she does occasionally - it seems real more of the time
She just gives off stress vibes - I was concerned and a friend visited who said I was being ridiculous and by the time she left the friend agreed she was stressed
Any suggestion of techniques to make her feel happier
