I have a feral cat that lives in my house. I have had her for two years, but have never been able to touch her. I had a vet come into my house and trap her and have her nutered and declawed and given her shots while she was at the clinic, but I know she was never dewormed. My problem is that when I trapped her, she had five kittens. I raised all of them, gave them there shots and adopted four of them to two special families. I kept the male kitten so the feral mother would be content. My problems is that now the kitten has developed feline asthma. I have run blood tests and had 3 x-rays to confirm. His lungs are clouded. He began coughing several months ago after we did some painting in the house. It seemed to trigger the cough. I thought it was fur balls, but soon relized he was in trouble. I keep researching to find a cure and am wondering if he didn't get worms that the two of them are passing through the litter box. I've never seen any, but I have watched the mother cat and some times she has a nerve twitch. Her body seems to twitch. Can anyone help me and tell me how to deworm them both.
