Chocolate Toxicity in Cats
Cats, and especially kittens, are known for eating things they are not supposed to. This can be a dangerous combination when there is chocolate around. Also, cats have an excellent sense of smell, making it fairly easy for them to find secret hiding spots for the chocolate.
Chocolate is derived from the roasted seeds of Theobroma cacao, which contains certain properties that can be toxic to cats: caffeine and theobromine. When ingested, these two ingredients can lead to various medical complications and may even prove fatal for your cat.
Symptoms and Types
Vomiting
Diarrhea
Increased body temperature
Increased reflex responses
Muscle rigidity
Rapid breathing
Increased heart rate
Low blood pressure
Seizures
Advanced signs (cardiac failure, weakness, and coma)
The amount and type of chocolate ingested is also important, as they are determining factors for the severity of the toxicity. The three types of chocolate that you must be aware of are:
Milk Chocolate
Semi-Sweet Chocolate
Baking Chocolate
Causes
Chocolate can become toxic for any cat. So be wary of feeding your cat anything that might contain chocolate and always keep it out of reach.
Diagnosis
Your veterinarian will perform a complete physical exam, including a chemical blood profile, an electrolyte panel, and a urinalysis. These tests will help determine if there is a chocolate/caffeine overdose. Blood can also be taken to test for theobromine concentrations, while an ECG is performed to help determine if the heart is showing any abnormalities in rhythm or conduction of heart beats.
