I'm so sorry. It sounds like Yasmin is very sick. If it is at all possible, get him in to a veterinarian as soon as you can. He is probably dehydrated and in need of some IV fluids. His blood sugar also may be dangerously low. If you are absolutely unable to get him to a vet, you can see if he will eat or drink if you hold it up for him. Please do not force water or food into his mouth, especially if he's extremely weak or not responding, as this increases the chances of him aspirating (inhaling the food or water into his lungs and developing pneumonia). You can also try rubbing a little honey or corn syrup on his gums--if his blood sugar is low this may temporarily help. However, ultimately the underlying cause will have to be treated. Please take him to a vet as soon as you can. Thank you for asking Petco Pet Education Center, formerly Petcoach, wishing you and Yasmin the best of luck.
