My 2 year old shelter cat that I adopted 6 months ago has loss about 1 ounce per two weeks according to the last weigh in today since January. She is now just over 6 lbs. She is petite to begin with. My vet wants to do blood work within a week or two, of which I will do. They mentioned possible kidney issues, but was wondering if it may be something else and wanted opinions in this forum. I'm thinking cancer, hyperthyroidism, or nothing at all. She is eating with no interference from the other 3 cats in the household and is very active. I was thinking that since she was caged for 4 weeks prior to me adopting her and then going to a home and becoming very active might have something to do with her weight loss, but it has been 6 months and she is very well adjusted in her new home as of 3 months ago. Thank you for any insight on the weight issue I am having with Princess.
