Case 11



Rintu is a 3-year-old castrated male domestic shorthaired cat.


Rintu's owners noticed that he was having full body tremors and experiencing intermittent crying starting at about 2 a.m., so they presented him to the veterinary hospital first thing this morning. The owners report no overt seizure activity, loss of consciousness, or convulsing. The owners wrapped Rintu in a towel most of the night because they thought he might be shivering due to cold. He has experienced no vomiting, diarrhea, coughing, or sneezing.

Rintu is a strictly indoor cat, and he has been healthy up to this point. The owners report no known trauma or changes or accessible toxins in his environment. He is fed a high-quality cat food and was eating and drinking normally until the tremors began. Rintu lives with a Labrador retriever named Max that is healthy, and they are known to play well together. Rintu is not receiving any long-term medications, and the owners have not given him anything for the tremors. They mention that they saw fleas on Rintu yesterday, so they applied a veterinary-prescribed topical flea product that they had for Max.
