Hi there! I understand how concerning it must be to see your cat losing weight without an obvious reason. Let’s explore a few possibilities to help you get some clarity.
Even with normal lab work and appetite, some underlying causes might not have shown up. Hyperthyroidism, common in older cats, increases metabolism, leading to weight loss despite a good appetite. Gastrointestinal conditions like inflammatory bowel disease (IBD) or food absorption issues can also result in weight loss while your cat seems to eat normally.
Other factors might include early-stage kidney disease or diabetes, where initial lab work might not catch subtle changes. Stress and anxiety can also trigger physiological changes causing weight loss, especially if there have been changes at home.
At home, ensure your kitty is eating high-quality food suitable for her age and health needs. Keep a weight log and monitor any changes in behavior or litter box habits, which can offer valuable clues.
Watch for signs of lethargy, vomiting, diarrhea, or significant behavior changes as these could indicate a more serious issue needing immediate attention.
It might be time to schedule a video consult with a vet through Dial A Vet. They can review your cat's history, give precise advice, and decide if more tests are necessary to get to the bottom of this. We’re here to help you ensure your furry friend gets the best care possible!
Cat losing weight despite normal lab work and normal eating. What could this be?
I’m really worried about my 8-year-old tabby, Luna. Over the past month or so, she’s been noticeably losing weight, and I can’t seem to figure out why. She’s still got her usual appetite and is eating the same amount as always, if not a bit more because I’ve been seriously packing her meals to help. We went to the vet last week and they ran a bunch of blood tests, but everything came back normal. I’m starting to panic a little because she’s always been on the chubby side and now her ribs are more prominent. I’ve checked for worms and even tried changing her diet to something higher calorie, but nothing’s working. Has anyone experienced something like this or have any suggestions? Maybe there’s something I’m missing. Luna’s my baby, and seeing her like this breaks my heart. Any advice would be so appreciated. Thanks!
