How Long Would A Cat Live Without Food. Healthy cats can survive for 1 week or more without food and just 3 days without water consumption. The repercussions of a poor appetite with subsequent reduction in body weight by at least 30 percent are particularly dangerous for overweight cats.
Significant and even life- threatening problems can occur if a cat is completely anorectic for a few days or partially anorectic for a few weeks. If your cat has not eaten for a day or two you should contact your vet immediately. Diabetes is one condition that can cause this.
The older a cat is the less time they can survive without any food.
I have a 20-year-old calico. The length of time a cat can live without food depends on the condition of the cats body. Your cat will likely become very sick after only 2 days of not getting any food or water. Going long periods without protein can cause cats to suffer from liver and kidney failure.
