My cat eats a lot, but I can feel her spine. Is she underweight?

Without seeing Mister in person, I can't say if he's too skinny or not, but it would be a good idea to have him seen by a vet this weekend. If he's eating and drinking, and acting otherwise normal, I wouldn't get too worried just yet. All cats are different shapes and sizes, and he may just be a bit thinner than her naturally. I hope this helps!

Cats tend to store fat inside the abdomen before they get a fat layer on the ribs. Here is a chart via which you can tell whether Indigo is too skinny: http://www.wsava.org/WSAVA/media/PDF_old/Body-condition-score-chart-cats.pdf

Overall being thin could be a result of an underlying metabolic, endocrine, or gastro-intestinal issue. (such as hyperthyroidism, diabetes,or inflammatory bowel disease) It would be best to have her evaluated by a veterinarian, and consider having blood work and urine tests run to see if there are any abnormalities. She is listed as unspayed--keep in mind that metabolism tends be slower once they are spayed. If everything on her lab work checks out to be normal, I would recommend you have her spayed for her overall health and for pet over-population concerns; another positive for her may be weight gain!

Hello. Feeling Gideon's backbone is not normal for a healthy young cat. There may be some issues going on with him that go beyond just feeding him more. Underlying disease or parasites or some type of maldigestion syndrome may be occurring. It may also just be his body type, but I would encourage you to have Gideon seen by your veterinarian to make sure all is well. Thanks for using Petco Pet Education Center, formerly Petcoach.

Hi there. You're correct that being able to feel the backbone or hip bones more easily than normal when petting your cat is a common early sign of weight loss. This could be caused by a number of different things - she may have some type of infection, a systemic illness like liver or kidney disease, or a GI problem like inflammatory bowel disease or chronic pancreatitis (weight loss can be the only symptom of these issues, in some cats). I would recommend taking Narla back to the vet for another exam to discuss your concerns and see if she has lost weight since last time. Your veterinarian may recommend blood work, x-rays, or other testing if needed to help diagnose the problem.

if only Nibbles could talk! It sounds like he has lost either some weight or muscle mass if you are now noticing the spine. It's hard to know why he would suddenly start eating cat litter. It could be he has a nutritional deficiency. It could also be a mental abnormality like Pica. I recommend to have him examined by the veterinarian for blood work and bring his food along too for the doctor to examine the ingredients. I hope this helps and please feel free to post any additional questions.

Your cat looks like a good weight to me.
