My 10 1/2 year old cat has gotten quite thin - should I be alarmed?

My sisters cat was 8 years old. She was a very healthy and active cat. Soon the cat, rosie, started losing weight. My family didn't really think much of it because she was eating normally. But after a few months rosie was extremely thin and slowed her eating, and her interest in playing. So my parents took her to the vet. Rosie had a form of cat diabetes. By the time they had taken her it was too late to do anything. All they could do was try to force feed her, and give her pain meds. All in all rosie end up passing away. Sorry if that got a little off track but yes...I would most certainlty take your cat to the vet. I can't guarantee that that is what it is of course, but it would be better if you found out sooner, because it is treatable. good luck, and I hope that your cat is fine.

I'm a Vet Assistant, and yes I think you should be a little alarmt since your Cat has an mature age, and anything that is different, can intricate something bad at that age, and it is better that you go to the Vet, when you notice something like this.
Does your Cat still urinate the same? Does she still clean her self, do you notice any fur change of some sort?
If she's thirsty all the time?

Like I said, I think you should got to your Veterinarian, just to be sure.

When my cat Patches lost weight, she was diagnosed with a thyroid problem. She was given one tablet of tapezol a day for the rest of her life. She lived until she was 20 years old. I mashed her pill into a teaspoon of watered down canned food, and she gobbled it right up.

I hope your cat has something easily treated and is back to herself in no time. Good luck.

I would say yes. Any major change in weight up or down is a cause for concern. My cat Tiger was diagnosed with kidney problems after he lost a lot of weight.

Better you need to take it to a veternity hopital. It's your responsibility to take care.

If she's eating and hungry all the time, and still getting thinner, by all means take her to the vet! I hope she is okay, and the vet can help her. I love animals. Take care, kelbel!
