Hi there, I've been doing quite a bit of online research but still do not feel resolved around this question. I have two large indoor cats that both exceed 15 pounds. I believe one is about 15 pounds and the other appears overweight at around 16-17 pounds. One cat will only eat Weruva chicken canned food now that I've transitioned him from dry food and the overweight cat eats Weruva, Wellness, Nutro (pretty much any grain free, healthy canned food in a pate he will eat) Weruva is known for their low calories per can and there is much debate online about it. Even though one of my cats is overweight, I'm still concerned they are not getting enough calories or I am not feeding them enough with the Weruva. They also seem hungry, meow a lot, and exhibit certain stressed out or "ocd" behaviours when they are meowing for food in between meal times and I don't give them any food. Would appreciate any feedback or information on how many calories cats need a day to be a healthy weight? I see a lot for average sized cats but my cats are not average size...They are just very large cats. Thanks so much for reading!
