I need help despreratly. I have a cat about 5-6 years old who has been raised with other cats. In november I moved into my boyfriends house, he has a young male siamesse cat who is very domminat. (my cat's name is shadow.) Shadow has always been a nerodic cat, always scared of everything and very timid, she was never abused and always very well taken care of, but a very weird paranoid cat. she was also considerably overweight. All of a sudden she has lost 2/3 of her body weight as if she was hidding under the bed never to emerge for food or water. I locked her in the bathroom with food and water and a warm place to sleep, she ate but now threw up large amonts of what apperaes to be food, but she did this several times last night in obvious places ike my bed and the bathroom rug and by the foot of my baby's bed. Is my cat just getting thin, is she starving to death, will she ide, do i need to get rid of the younger male cat, i am so confussed as to what would be the problem with an otherwise healthy cat. it amazes me to think that a cat would be so scared of another cat that they would rather starve to death. am i just abusive and neglectful, i would hate to think so, i am so scared and concerned, what am i to do. i am also not financially in a position to pay hundreds of dollars on a cat as i am a single mother. please anyone with help, advice, a link on where to look for information, anything please email me. i am desperate, thank yo and god bless you.
