My cat won't eat or drink after switching from wet to dry food.

Try warming the food slightly or mixing in a teaspoon if plain baby food. If he doesn't begin eating in the next 24 hours, have him physically examined by your veterinarian. A cat that does not eat for 2+ days is a serious risk of developing liver disease which may complicate any underlying condition.

Poor kitty! If she is vomiting and not eating or drinking, this is a serious problem - even if the problem began because of stress, she will quickly become dehydrated if this continues. I would recommend having her examined by a vet as soon as you can - he/she can do blood work and x-rays if needed to find out what's wrong and get her started on IV fluids and other supportive care if needed.

Thank you for trying to help this lady out. Anytime a cat is not eating or drinking this is reason for concern and an immediate visit to the vet is warranted. I recommend using Feliway pheromone spray (you can pick this up at PetCo) and spraying it on a towel that you place in the carrier. Hopefully this will entice the cat into the carrier. Good luck!

Poor Tomasina. It's actually very serious when a cat won't eat, as if they go long enough without eating (about 72 hours), they will develop a fatty liver. A fatty liver is fatal without treatment, so you want to avoid that. I'd have her checked out by a vet today. While the change in diet can cause stomach upset in the form of vomiting and loss of appetite, it could also be she is sick.

I would suggest you take Alice to your vet for an exam to have her teeth checked. She may have an issue that is causing her pain to the point where chewing hard food hurts. It is fine to mix wet food with dry. I would need to know what type/brand of food you are feeding to give you any idea of how much you should feed her. Every single type of food you see has a different amount of calories per cup or can of food so there is no blanket amount that I can say to feed her. I can tell you that the average indoor cat should eat about 20 calories per day for every pound of body weight. So, if she is 10 pounds she can eat about 200 calories per day. Just look at the bag/can of food you are feeding as it should tell you how many calories is in it and then you can go from there. Do not exceed the 200 calories per day. Hope this helps.

Take Piper back into a vet immediately. It's extremely serious when a cat won't eat, and if they don't eat going on 72 hours, they will develop a fatty liver which is fatal without treatment. Please take her into a vet now. Best of luck.

Some cats prefer dry food (biscuits) and when they eat only dry food they drink much more water. staring is not an uncommon behavior for cats so i don't think this is a problem. If you think her appetites is going down and that she is after all drinking much more than she should, i would recommend taking her to the vet for a checkup and blood test.
