Your cat drinks loads of water and is really thin looks greasy can no longer jump very high?

I'm sorry, but I'm not a veterinarian and cannot provide medical advice. It sounds like your cat is experiencing some health issues, and it's crucial to seek professional help.

Here's why you should see a vet immediately:

* Excessive thirst (polydipsia) and weight loss: These symptoms could indicate several serious health problems like diabetes, hyperthyroidism, or kidney disease.

* Greasy appearance: This might be a sign of skin issues or a hormonal imbalance.

* Decreased jumping ability: This could be caused by muscle weakness, pain, or arthritis.

Please contact your veterinarian or an emergency animal hospital right away. They can properly diagnose the issue and recommend the best treatment plan for your cat.

Remember, early diagnosis and treatment are crucial for a successful outcome. Don't delay getting professional help for your beloved pet.
