I am quite puzzled as to why Tanaka is still so thin as all the boys are about 5 kgs. Megat is not 5 kg but Dr Ly said he is a little fat. Tanaka is very light to hold and I had seen the vet last year about his weight. The vet said that there is nothing wrong with him and I know at just about 4 kg, he is ok. I noticed however that he gets quite hungry at night and hardly ever eats in the pm, although he does eat a little in the morning. then it struck me that all the boys have been eating the kibble and as the youngest kitty, he is always the one who has to give in. So I decided to give him his own kibble bowl on top of the cage and I am glad to see that he eats from there several times a day. So maybe I have cracked it!
