My cat ate Bog Bilberry — what to do

Step by step

  1. Take bog bilberry away and remove any plant material from your cat's mouth so they cannot eat more.
  2. Note roughly how much was eaten and when — this helps the vet judge the risk.
  3. Do NOT induce vomiting unless a vet or poison-control specialist tells you to.
  4. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 (a consultation fee may apply) and follow their advice.
  5. Watch for drooling, pawing at the mouth, vomiting, loss of appetite, or lethargy, and bring a leaf or photo to the appointment.

This is general guidance, not veterinary advice. Pets vary, and a reaction may be to soil, fertiliser, or pesticide as well as the plant. When in doubt, call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435.

My cat ate bog bilberry — FAQ

Is bog bilberry poisonous to cats?

Yes — the ASPCA lists Bog Bilberry (Vaccinium uliginosum) as mildly toxic to cats. Vaccinium uliginosum is not listed on the ASPCA Toxic or Non-Toxic plant database. The ripe berries are widely consumed by humans and wildlife and are broadly considered safe; a 2024 phytochemical review found no evidence of toxic alkaloids or strongly harmful secondary metabolites. However, historical European folklore warned of inebriation (now attributed to natural fermentation of fruit), and the plant's safety for cats and dogs has not been formally confirmed by ASPCA. On a precautionary basis it is classified as mildly toxic to pets; do not allow pets to graze it freely and consult a vet if significant ingestion occurs.

How serious is it if my cat ate bog bilberry?

Bog Bilberry is mildly toxic, so most cats get short-lived mouth irritation, drooling, and vomiting rather than a life-threatening reaction. It is still worth a vet call to be safe, especially if your cat ate a lot or symptoms persist.

What symptoms should I watch for?

Signs usually appear soon after chewing: drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy. Vaccinium uliginosum is not listed on the ASPCA Toxic or Non-Toxic plant database. The ripe berries are widely consumed by humans and wildlife and are broadly considered safe; a 2024 phytochemical review found no evidence of toxic alkaloids or strongly harmful secondary metabolites. However, historical European folklore warned of inebriation (now attributed to natural fermentation of fruit), and the plant's safety for cats and dogs has not been formally confirmed by ASPCA. On a precautionary basis it is classified as mildly toxic to pets; do not allow pets to graze it freely and consult a vet if significant ingestion occurs. Any worsening or persistent symptoms warrant an immediate vet visit.

Should I make my cat vomit?

No — do not induce vomiting unless a vet or the ASPCA Animal Poison Control Center specifically tells you to. The wrong action can make things worse. Call (888) 426-4435 and follow professional advice.

How do I stop this happening again?

Keep bog bilberry well out of reach, or swap it for an ASPCA non-toxic plant — see the best cats-safe plants list.
