Overweight and the feline gut microbiome - a pilot study

Area of Science:

• Veterinary Medicine
• Microbiology
• Animal Science

Background:

• Obesity is prevalent in cats, mirroring trends in humans.
• Gut microbiota alterations are linked to obesity in humans, but unstudied in cats.
• Understanding feline gut microbiome is crucial for addressing obesity.

Purpose of the Study:

• To compare the gut microbiota composition of lean cats with that of overweight and obese cats.
• To investigate potential links between feline obesity and gut microbiome changes.
• To establish a baseline for feline gut microbiome research in obesity.

Main Methods:

• Analyzed fecal samples from 77 rescue cats using 16S rRNA gene sequencing.
• Assessed body condition using a 9-point scoring system.
• Compared DNA yield from rectal swabs versus litter box samples.

Main Results:

• Overweight and obese cats exhibited a significantly different gut microbiota compared to lean cats (p < 0.05).
• No specific bacterial groups were identified as solely responsible for these differences.
• Rectal swab samples yielded higher DNA concentrations than litter box samples (p < 0.0001).

Conclusions:

• Feline obesity is associated with an altered gut microbiome.
• Further research is needed to identify specific microbial changes and their implications.
• Rectal swabs are a more effective method for DNA collection in feline fecal studies.
