My cat has been vomiting a lot lately and has had an immense appetite. This has not happened before.
Vomiting is a very nonspecific symptom that can occur due to different reasons.
If your cat is not expelling hair with the vomit, it is advisable to take him to your veterinarian for a general examination and, if necessary, a basic analysis so that your vet can determine if something is wrong with your cat. It is necessary to discard problems in the oral cavity and digestive system.
All the best,
