Hi I have a question regarding my cat she has been having grey colored poop for the last 3 days. Today it had a little brown color to it but was mainly grey.She has been meowing alot but she is a overweight cat and tends to meow like that to get fed so I don't know what to think. The meowing just started tonight but she is also playing alot like running around the house fast, chasing her own tail etc. She has been eating good if anything she eats too much lol Her energy level seems good. I just would like to know what could be possibly causing this and if it is anything I should be worried about. Thanks for any advice and have a great day:)
