when I first got mia (a mother cat) from a shelter she was a bit frightened and agressive, she wanted to be with me a lot but then she would hide under places if dogs barked or trucks past and she had obvious food anxieties she would grab food and drag it around and meow to her kittens who had been adopted out, she would also grab kitten plush toys and drag them or socks as if they were her kittens, a few times she has been agressive towards me and she does not like being in confined small places she can't get away so I avoid being near her in the hallway so she does not feel threatened. but overall she is a good cat who has learnt to adapt to our family. her and snug have had a few bad fights where he has made her bleed and attacked her, and I have had to punish him and tip water over him and chase him away from her. but mostly they are good and all get on. they know to behave if the water spray bottle comes out or a rolled up newspaper. I don't like them fighting.
