About 6 months ago I was gone for three weeks and my husband said that Jasper seemed to get very depressed about a week and a half into my absence. He started to give him a couple of spoonfulls of tuna a day as a treat and it seemed to help him feel better until I got home. Now he thinks that he has to have it constantly! I have tried to ignore him but he follows me around biting my ankles and meowing loudly if I don't give it to him in the morning and the evening. My question is that I don't know if giving him the tuna is good for him or not? If it won't hurt him then I'm not going to worry about it but I have read that pregnant women shouldn't eat too much tuna due to the amounts of mercury present in the fish and since cats are so small I didn't know if this was a problem for them too. Does anyone else??
