With its delicate flowers and versatility in the garden, it’s no wonder lobelia has become a staple in many plantings However, this popular perennial does come with some risks, especially for curious cats. Is lobelia poisonous to cats? Let’s take a deep dive into lobelia’s toxicity and how to keep your feline friends safe
An Overview of Lobelia’s Toxicity
All parts of the lobelia plant, including the flowers, foliage, seeds, and stems, contain toxic alkaloids that can cause poisoning when ingested. The highest concentration is found in the leaves and seeds.
Lobeline is the main toxic compound in lobelia. While toxic, in small doses this chemical acts as a stimulant, while large doses trigger respiratory paralysis. Clearly, it’s a substance to be treated with caution.
Both annual and perennial lobelia varieties contain these toxic elements and should be kept away from cats. Some common species include:
- Cardinal flower (Lobelia cardinalis)
- Great blue lobelia (Lobelia siphilitica)
- Trailing lobelia (Lobelia erinus)
- Indian tobacco (Lobelia inflata)
What Happens if a Cat Eats Lobelia?
Lobelia rarely causes fatal poisoning in cats, but ingesting any part of the plant can lead to concerning symptoms that require prompt veterinary treatment.
Within a few hours of eating lobelia, cats may exhibit:
- Excessive drooling and vomiting
- Abdominal pain and diarrhea
- Depression, lethargy, or muscle weakness
- Rapid breathing and heartbeat
- Disorientation or tremors
- Collapsing episodes
Without medical intervention, these symptoms can progress to potentially life-threatening respiratory failure in severe cases of lobelia poisoning. Never hesitate to call your vet if you notice these signs after your cat accessed lobelia. Quick action greatly improves the prognosis.
Why is Lobelia Toxic to Cats?
Lobeline and other alkaloids found in lobelia act as stimulants and depressants, sending mixed signals to the body’s nervous and muscular systems. The result is many of the concerning symptoms seen in lobelia poisoning.
Specifically, lobeline triggers the release of epinephrine, causing rapid breathing, increased blood pressure, and elevated heart rate. It also activates muscles, leading to tremors and muscle weakness as they become overstimulated and exhausted.
Vomiting results from lobelia’s initial irritating effect on the gastrointestinal tract. Diarrhea and abdominal pain follow as the digestive system tries to expel the toxin.
How Much Lobelia is Toxic to Cats?
Any amount of lobelia ingested by cats should be cause for concern. The exact toxic dose depends on the size of the cat and other individual factors. Kittens are especially vulnerable even to small amounts.
Immediately call your vet if your cat ate any part of a lobelia plant to assess toxicity risk and recommend treatment steps. Don’t wait for symptoms to appear, as prompt action leads to better outcomes.
With aggressive veterinary treatment, most cats fully recover from lobelia poisoning. But prevention is always better than cure when dealing with toxic plants.
Are Cats Naturally Drawn to Lobelia?
Interestingly, cats do not seem to be tempted to taste or chew on lobelia plants. The strong scent alone deters most felines. Instinct tells them to avoid this toxic plant.
However, kittens or curious adult cats may still nibble plants if given unsupervised access. It’s also possible for a cat to ingest lobelia through grooming pollen from their fur after brushing against the plant.
So while not a natural temptation, access should still be restricted and any exposure treated seriously. Don’t assume your cat will instinctively avoid lobelia.
How to Keep Cats Safe From Lobelia
Here are some tips to reduce the risk of lobelia poisoning in cats:
-
Grow lobelia in hanging baskets or elevated planters that cats can’t access.
-
Add physical barriers like fencing or wire guards around garden lobelia.
-
Keep indoor lobelia in a cat-proof area like a spare bathroom or screened porch.
-
Deter curious cats by spraying leaves with bitter apple spray. Reapply after rain or watering.
-
Remove and replace lobelia with non-toxic plants like catmint or catnip.
-
Never force cats to interact with lobelia against their will.
-
Seek immediate veterinary help if poisoning is suspected.
Taking a few simple precautions goes a long way in protecting curious cats from toxic lobelia. With vigilance and quick response, cat owners can enjoy this versatile plant safely.
Veterinary Treatment for Lobelia Poisoning
If a cat eats lobelia, contact your vet or the ASPCA Poison Control Center right away. There is no home treatment for lobelia poisoning.
Veterinary tactics focus on quickly eliminating toxins, counteracting symptoms, and stabilizing the cat through the ordeal. Common treatments may include:
- Inducing vomiting to remove lobelia from the stomach
- Administering activated charcoal to bind remaining toxins
- Intravenous (IV) fluids to prevent dehydration
- Medications to control vomiting and diarrhea
- Sedatives for agitation or tremors
- Oxygen therapy for breathing issues
- Monitoring heart rate and rhythm
- Hospitalization for multi-day supportive care
With aggressive decontamination, symptom management, and monitoring, most cats recover fully with no lasting effects. But home care and delaying veterinary treatment severely reduces the chances of a positive outcome. Don’t take a “wait and see” approach.
Can Lobelia Be Used as Feline Medicine?
When prescribed in very small doses by a vet, lobelia can occasionally be used as a medication for cats. For example, it may help relieve respiratory congestion in bronchitis.
However, lobelia should never be given to cats without veterinary guidance and oversight. Incorrect dosing can easily cause poisoning.
This plant has no benefits in cats when used as an herbal or home remedy. Leave any internal use of lobelia to the professionals.
