My cat has inflammatory bowel disease. When her sister was alive, the vet recommended I feed both my cats Eukanuba intestinal biscuits. Simone, probably because of the Prednisalone medication, has a dry skin condition. When the weather is hot, she is prone to her fur clumping. This condition worsens with the onset of wet weather during summer. She is a Maine Coon and has a mixture of long and short hair. She has a thick coat. Earlier this year, she had a severe bout of inflammation of her colon and stomach, to the extent that I think she developed an ulcer. She couldn't keep anything down. I switched her to the IAMS Mature chicken pouches to encourage her to eat because she had lost her appetite. The condition of her fur and skin improved, so much so that she enjoys being groomed and I haven't had to cut any fur clumps off her for 6 months. She also hasn't vomited up a furball during this time and her bowel movements, are slightly improved. But she has gone from weighing 4.7 kg to 4 kg. This could be through the loss of her sister 2 months ago (no competitive eating, loneliness, less exercise). But I'm not sure. She is eating less Eukanuba Intestinal biscuits. Should I change her hard biscuits/
