Cat excessive hunger My male part Siamese cat is ALWAYS hungry (for last 5 months).I switched to Hill's I/D (from W/D), plus dry W/D. Still constant hunger. Vet says blood panel and 2 ex-rays showed normal. Could it be parasites? Thank you!

First, I am seeing a vet about this. Just trying to get some other thoughts. My Rana-cat has always been small... I think her heaviest weight was 6 pounds, 4 ounces. But she's always been in really great shape... very athletic, the kind of cat that vets love to point out as what a healthy cat...

My 10 yr old in the past couple of days has lost weight, seems weak, and staggers when he walks. He doesn't seem to have a fever and purrs as normal. What could be wrong? Is it just his age and something expect with age:confused? My two other cats seem fine.

For the past 2.5 months my husband cannot get enough liquids in him. He has lost 12-15 pounds and gets us 5-6 times per night to urinate. All new things for him. He always had a strong sex drive that also has changed. He will be 45 years old this month. Any idea what this could be?

Hello all.. I'm a 19 year old male and I know it's not healthy to loose more then 2 lbs a week but I'm going to aim for 4-5 lbs a week. But is this VERY dangerous? My body needs 2200 calories a day to maintain my weight, so instead I'm going to eat 1200 calories which is 1000 calorie difference...
