ABSTRACT
Amanollahi R, Soltaninejad
H, Ghasemkhani N., Cannabis poisoning in a cat, Onl J Vet Res., 24(7): 434-437,
2020. Reports of unintentional cannabis poisoning have been described in
children and dogs, but not to our knowledge, in cats. Owner reported
that the animal accidentally ingested cannabis. The 3-year-old
male Persian cat weighing 3.2 kg, presented severe anorexia, frequent vomiting
and constipation for 2 days. Body temperature
was only 35.7C, but pulse 167/min and respiratory rates 52/min with severe
jaundice. Cat was treated IV with 40 mL/kg 0.9% saline + 5% dextrose, 0.5mg/kg
IV metoclopramide and 1mg/kg pantoprazole for gastritis for 24 hours without
improvement. Hematology revealed red blood cell count (RBC) of 1.65×1012/L,
hematocrit 8.7%, platelets 29×109/L,
hemoglobin 3.2 g/dL, aspartate 639 IU/L and alanine
transaminases 430 IU/L, alkaline phosphatase 126 IU/L, bilirubin 4.27mg/dL, albumin 7.6g/dL and urea
nitrogen 57.0 mg/dL but total protein only 4.27 g/dL. RBC and protein were present in urine. Hematology and
urine analysis suggested severe liver and kidney failure. Radiography showed gastric
obstruction and surgery revealed cannabis entangled in a hair ball in pyloric
sphincter. Despite treatments, the cat did not survive after surgery due to poor
clinical condition. At necropsy the most affected organs were liver, spleen,
and kidneys; which were remarkably large and hemorrhagic. As cannabis consumption
is increasing in humans, accidental poisoning of companion animals may
increase.
