Did you think we'd forgotten about cats? Well we had a little guy named Calvin give us a good reason to write a blog about cats. Calvin decided to help his mom fix the dogs' breakfast one day last week by eating half of a Rimadyl tablet. Now this could have been pretty bad news. Cats are missing the enzyme system that the liver uses to metabolize nonsteroidal antiinflammatory drugs, or NSAIDs. As a result of this inability to metabolize these drugs a very small dose can easily become toxic. These drugs, members of the aspirin class, cause stomach ulcers and kidney failure in high doses. Sounds a little like Dixie, the counter surfing dog from a previous blog, huh? Calvin required two days of intravenous fluids and close monitoring of his kidney values. He's doing great.
Now there are some NSAIDs that can be used with caution in cats. Always make sure you use these drugs only under the direction of your veterinarian. And be sure to report any lethargy, loss of appetite, or increased urination to your veterinarian if your cat is receiving one of these drugs. These signs may indiciate an adverse reaction to the medication. As with all toxicity problems early diagnosis and treatment are paramount to a full recovery.
A related drug is acetaminophen, or Tylenol. This is very dangerous to cats. Never administer any product containing this drug to any cat. In case of accidental exposure seek veterinary care immediately. A very small amount of acetaminophen can be fatal in cats.
