As a cat parent, there’s a lot you may do, such as making sure their nutritional needs are met, getting them groomed, and making regular healthcare appointments at the vet. Doing so ensures that your feline friends stay in the best of health. However, occasionally, one may notice their cat isn’t well. This may occur because of factors including environmental conditions and age. But here are six signs that may require the intervention of an expert: Changes in appetite Though changes in appetite could be normal in cats, they should not be overlooked. If your cat stops eating food entirely or is only munching on tiny bits of food, that could indicate the onset of severe problems known as fatty liver or hepatic lipidosis. On the contrary, overeating may be a sign of hyperthyroidism, especially in older cats. Furthermore, even if a health complication doesn’t cause it, one must consult with a vet to prevent overheating and the gain of pounds. Sudden lethargy If your cat is always lethargic, that could be a cause for concern. Felines that lie around for too long, have low energy levels, or sleep excessively might indicate that something is wrong with their health. Increased thirst Drinking lots of water occasionally due to conditions like higher temperatures is normal.
