your cat sounds just like mine acted before she did end up too ill to live form her kidneys shriveling up.You should get a blood test and a urine test.
If its early enough you can catch it.if you wait it will be too late if that's what it is. also CATS ORIGINATED from the desert. they need more water then they can drink. Make sure you give them a half a can a day of moist canned food. I prefer the gold brands dry and wet...my cat lost weight slowly ,then all of a sudden was way to thin. by the time I figured all this out,her kidneys were too shot....hope its nothing,but I just had to share in case!
