Is it normal for my adult cat to eat less and seem lethargic?

I wouldn't think that a decrease in appetite and weight loss would result from a diet change. Some cats can be quite picky and will stop eating a food they previously liked or be hesitant to try a new food, but eventually these cats will eat once they get hungry enough and picky eating should not result in significant weight loss. I wouldn't be concerned about changing to an adult food in an 11 month old cat either - Kovu was probably very close to his adult height by that point. I think seeing your veterinarian to have Kovu's weight checked and for a complete physical exam sounds like a great idea, and if they feel he is in good health you can discuss trying to find good quality diet that he seems to like and then monitor his weight closely.

Monitor Cash very closely for any other signs of illness such as vomiting, loose stool, sleeping more or not playing as much. If you see anything else that looks like an illness, have him examined. If you notice that his appetite is continuing to decline, have him examined as well. Sometimes you can see the appetite have some minor variation. When in doubt, have him examined. I hope this helps and please feel free to post any additional questions.

It is probably not normal. I suggest you schedule an exam with your veterinarian for your cat. Your cat may have dental problems (gingivitis and/or tartar, tooth infections), diabetes or another endocrine disease. Oder kitties also often have problems with their kidneys. A thorough clinical exam and blood tests can at least rule out any serious disease that could cause eating less than usual.

If Zelda is still eating a normal amount of her usual food this may simply be a change in preference - just like people cats sometimes decide they don't like a food as much as they once did. It's also possible that she isn't eating as much as she gets a bit older and is not growing as rapidly. If she seems to be eating a lot less overall or losing weight this could be a sign of an underlying illness and you should have her examined by your vet.

What you are describing does not sound normal. Certainly adult cats will eat a little less than kittens if they are less active, but it sounds like Mischa's appetite has decreased pretty dramatically. You can certainly try changing brands or flavors of food in case there is something she does not like about her food. I also do not recommend mixing the canned and dry food because if they do not eat it all at once, moistening the dry food can cause bacterial growth. So, if you feed both types of food, just put them in seperate bowls. If you try a different food and Mischa still does not eat well, I would recommend having your vet examine her and possibily run some bloodwork to makes sure that everything is normal. Good luck!

The exact amount of calories that a cat needs certainly depends on their weight and activity level, but will tend to decrease slightly when a cat reaches an adult age. So, that might be why Baluu is eating less canned food than he used to. If he did not used to eat the dry food along with the canned food, then that would also account for why he is eating less canned food. In general, we usually recommend about 5 ounces of canned food for each 10 pounds of body weight if they are not eating any dry food. Based on that, it sounds like Baluu is eating a sufficient amount since he is also eating some dry food. If it seems like Baluu is losing weight, then I would recommend having your veterinarian examine him to make sure there isn't something going on internally. Otherwise, I would suspect that his metabolism is just slowing down a little and he doesn't need as much food as he did when he was younger. Some cats really desire some variety in their food, and it sounds like Baluu is one of those cats. Good luck! I hope that answered your questions.

A 3 pound weight loss is indeed significant and not normal. There could be many reasons for this, and there is just no way to pinpoint the cause without a hands-on exam and possibly blood work. I suggest you take your kitty to a veterinarian for a wellness exam.
