Tuna is good or if you cook chicken and drain off the fat then put that in her food that will really help. I had a veterinarian recommend feeding a cat I had once chicken fat so that is how I did it. I only fed her moist food and I went with the higher end one that had the highest fat in it and then I added chicken fat. Worked like a charm.
feed it Meat, Chicken, part of your sandwich, hand feed it, my friends black cat is FAT, he feeds it like that...it is like everytime he eats something he gives some of his food to the cat also...Probably unhealthy though
Mix dry and wet together until it's like cookie dough consistency. Feed kitty the mixture once in the morning and at night. Always have dry food available in an automatic feeder throughout the day. Always provide plenty of water for kitty.
