Why would a 16 year old cat lose weight and fur with no appearance of sores?

My cat is 16 years old. She has generally been a very healthy cat, with a good appetite for food and activity, and somehow managed to avoid getting fleas all but twice despite being an indoor/outdoor cat.

She had fleas for the second time about a month ago. I bought Sergeant's flea spray for cats to use on the furniture and put a flea collar of the same brand on her.

About two weeks ago I noticed she had (seemingly very suddenly) lost a lot of weight. I could probably wrap my hand around her if I wanted to and if she'd let me. She's also begun scratching or biting me if I touch her torso.

Today I noticed she seems to be going bald. The fur on both sides of her torso is short and thinned out, so you can plainly see her skin on each side from behind.

There are some hard yellow bumps on her spine near her tail, but there is still plenty of fur there. There are no sores or lesions of any kind on the balding areas.

I started worrying when she lost weight; now I'm just plain scared.

Update:

Thank you. I just took the flea collar off and will be cleaning her up and vacuuming the furniture incase it was the flea treatment. I'll give her about a week to see how that goes before I freak out and bother the vet. It was her first time with a flea treatment and someone mentioned I chose a harsh brand so I'm going to hope that was it unless she gets worse.

Update 2:

I didn't double dose her. I put the collar on her and the spray on the furniture (between mattresses on the bed and between cushions on the sofa and chair), since the fleas had spread throughout my house.

She eats, drinks, and expells the same as always. Her behaviour hasn't changed aside from the addition of biting me, and she doesn't seem to be in pain or discomfort.

    Sargent's is a really harsh brand. My cat looses it's hair on the spot where you put the topical treatment.

    I would give the cat a bath and not use the product again.

    I had one cat that lost most of her hair... she now looks like the hairless cats. (well she does have some thin hair) but she never grew it back even with all the vitamins I gave her. (she was around 17 when it happened and is 21 now)

    I had all kinds of blood tests done and nothing ...everything came back normal.

    I did get some results from giving her some milk thistle (which is for the liver)

    I suggest taking to your vet... get some tests done and then start treating with vitamins.

    You can use human vitamins for cats but in smaller doses)

    Re weight loss... natural in old age w/ cats.

    good luck

    By putting flea spray AND a collar on her at the same time, you "double-dosed" her.

    Take her to the vet and have a checkup. If these bumps near her tail are related to the "flea problem", she may still have some. Sergeants isn't the best flea product around!

    If she's scratching her torso enough to lose hair, she may be "itchy", and the vet can give her a shot to get rid of the itchiness. He may also prescribe some antibiotics for any underlying infection that has been caused.

    Another thing......at 16, your cat is 80 in human years, so she could be developing some age-related illness. Drinking a lot, eating but still losing weight, is a sign of diabetes. Have her checked for that. If she doesn't have diabetes....GREAT.......but, if she does, catching it early so she can be treated is something you won't regret.

    Hope this helps........Good luck

    the weight loss, im not so sure about, but it could be related to an allergic reaction to the flea treatments you used. both the collar, and the spray. i could clean the furniture the best i could, give her a bath after removing the collar with a mild conditioning soap. no matter how much she might fight you in the bath.

    And try to use something like front line treatment for fleas. It works wonders for me. Well for my cats! You can by 1 month treatments in some pet stores, and possibly at the vet. Instead of having to buy months worth, which is costly.

    Hi, I am a cat behavior, and I hate to tell you this, but it also happened to my little girl cat of 18 yrs who passed away of kidney failure.

    16 X 7 to human year is 112 years old.

    You cat symptoms sound like kidney failure, and you should have it the VET check.

    If I can go back in time, I would not have done the sub Q and enjoy her senior years, there are holistic food and medicine now at your regular pet store.

    Does she seem to be in pain? Is she eating and drinking well?

    My nan, had a cat the same age as yours. And he went like that, he went to the vets - had his tests, and it turned out to be his kidneys. He lived for 3 years after though.

    The bumps could be indicative of cancer. The weight loss could be due to a tape worm (thru the fleas) or due to cancer or other medical condition. Due to her advanced stage in life, you should take her to the vet for a thorough check up to see what's going on.
