Three cats experienced unexplained fat malassimilation. While pancreatic enzyme supplementation improved fat digestion, post-mortem exams revealed enteropathy and pancreatitis, not exocrine pancreatic insufficiency, leaving the cause unknown.

Area of Science:

  • Veterinary Medicine
  • Gastroenterology
  • Comparative Physiology

Background:

  • Investigating causes of weight loss and malassimilation in cats.
  • Evaluating diagnostic challenges in feline gastroenterology.

Observation:

  • Three cats presented with unexplained weight loss despite adequate food intake.
  • Confirmed steatorrhoea (fat in feces) via 72-hour fat assimilation tests.

Findings:

  • Dietary supplementation with pancreatic enzymes improved fat digestibility by twofold in all cats.
  • Fecal smear analysis indicated fat maldigestion and malabsorption, with minimal starch or protein maldigestion.
  • Post-mortem examinations revealed enteropathy and pancreatitis, but ruled out exocrine pancreatic insufficiency as the primary cause.

Implications:

  • The precise cause of fat malassimilation in these feline cases remains undetermined.
  • Highlights the difficulties in diagnosing malassimilation in cats due to limitations in current investigative tests.
  • Suggests further research is needed to develop reliable diagnostic tools for feline malabsorption disorders.
