Your cat should be regularly monitored to make sure it doesn't gain or lose weight. Your vet needs to examine your pet regularly and review their notes to see how your pet is progressing. Your vet will probably ask you to monitor how much your cat drinks to help monitor progress. At other intervals your vet may want to take blood samples from your cat - and may need to keep your pet in hospital for a day to do this. If you have any concerns about any aspect of your pet's treatment discuss them with your vet.
