Is Blueberry Safe for Russian Blues?

Blueberry is not directly toxic to Russian Blues but must only be offered occasionally and in very small amounts. Not toxic but cats lack receptors to taste sweet fruits for Russian Blues. Feeding too much or too frequently causes digestive problems and potential long-term health issues.

Minimal benefit — cats are obligate carnivores. When introducing Blueberry for the first time, start with a smaller amount than recommended and wait 24 hours to check for any adverse reaction before offering more.

💡"In moderation" means once or twice a week maximum — never daily.
💡Monitor your Russian Blue for 2–4 hours after first giving Blueberry for vomiting or unusual behaviour.
💡If your Russian Blue has any pre-existing health conditions, ask your vet before offering Blueberry.
💡When in doubt, leave it out — there are plenty of fully safe treat alternatives.
