I am sorry your girl is not feeling well. I am concerned that she may have ingested a toxin outdoors. Could she have gotten something on her fur and groomed it off?
Has she been tested for FELV and FIV? as those can cause symptoms.
There are a few possibilities for these symptoms. I will try to cover everything.
Weight and hair loss is usually related to hyperthyroid. The cats eats great but the excess thyroid hormone burns up all the calories.
The problem is that this disorder can lead to your baby developing diabetes, high blood pressure and other ailments.
We do have excellent meds for this but is is necessary to do a T4 thyroid blood test.Any other thyroid test can be inaccurate.
It can also be related to renal issues especially if there is excess shedding because the hair becomes very dry.
Stress weakens the immune system and can lead to illness.Dental disease also depresses immunity and sends bacteria into the organs.
You are absolutely correct to be concerned, dehydration is very dangerous.Sometimes it is caused by renal issues that begin with UTI's
Not only can infections damage your baby's urinary tract but her immune system as well.
The type of food is VERY important. Hi protein and MEAT puts weight on without unnecessary fillers.But protein is contrainicated if the cat has renal disease.
In addition, UTI's must be treated with an effective broad spectrum antibiotic like Clavamox or clidimycin and for a long enough duration so all bacteria is eradicated. If not, they will refluorish, stronger and more resistant and reinfect her . In addition, the bacteria can become tolerant of the same antibiotic so the medication should be varied for best results.
It is better if she does not eat dry food. Canned will ensure she gets adequate fluid. Cats her age can become dehydrated more easily. A dehydrated cat is not motivated to eat.
She should also be checked for:
All of these are treatable so try to have her seen soon.
