Fresh colorful flowers enhance the ambiance of a house, giving a lovely touch to any home. But cat guardians should be aware that many of these are toxic plants and can pose harm to kitties! Quite frankly, not all toxic plants are fatal when eaten, but most often than not, cats end up at the vet from sampling on toxic houseplants.
While Lily is widely known to be particularly poisonous to cats, many plants are dangerous if eaten. Seeds, pollen, needles, leaves and flowers can all be potentially harmful for cats. Often they ingest substances from toxic plants while grooming themselves due to seeds or pollen being trapped on their paws or in their fur.
Why Are Lilies Very Bad For Cats?
Although kitty may show little interest in eating them, it is extremely risky if they come into contact by rubbing their body against lilies’ flower pollen before licking their fur without thinking.
Easter Lily and Tiger Lily are a few types of toxic plants for your cats. All parts of lilies are poisonous to our furry friends. Even a bite of them can pose a lethal threat to their lives from severe kidney failure. The best way to save felines from lilies is by completely keeping it off your property. To clarify, by not purchasing one at all. If you still want to purchase these flowers, make sure to keep the gorgeous collection in a room where your cats have no access to.
Keep Your Cat Safe From Toxic Plants
Cats are generally finicky about what they put in their mouth. Especially for outdoor cats with freedom to explore other things other than sampling peculiar vegetation, poisoning from toxic plants rarely happens. However, confined indoor cats that are inquisitive and bored are likely to play with and chew on toxic plants, thus becoming sick. Despite this, they can also accidentally consume toxic pollen when grooming themselves.
It’s cats’ instinct to eat grass as they need it to cleanse their digestion, on top of liking to chew on plants for the sake of curiosity. When there is none, they will turn to less decent bouquet plants like particularly hazardous Dumb Cane (Dieffenbachia) and lilies. For this, you can provide them cat-friendly plants like catnip, cat thyme or mint. But keep the portions small. While it’s normal for them to be tipsy or wild after nibbling on the catnip, excessive consumption in a short time may lead to vomiting and diarrhea.
To avoid possible poisoning cases for outdoor cats, work with your neighbours to remove toxic plants from the neighborhood by informing the list of toxic plants written in both common and scientific names. This can ensure that any additions to the gardens will be safe. Be sure also to keep uprooted plants and hedge clippings out of your cat’s vicinity. This is because the sap of damaged stem may trigger skin irritation. Further, roots, bulbs, and rhizomes can cause the most hazard on cats once ingested.
Does Spraying Toxic Plants Work To Stop Cats From Eating Them?
Using a taste-deterrent spray on your houseplants may work as cats don’t like the taste, but it’s a tedious process that requires you to reapply daily to keep them at bay. Most cat guardians struggle to water their plants weekly, so undoubtedly, they will most likely fail at spraying the plants every day. Furthermore, plants that are more porous like ferns, begonia, and moss, seem to suffer in health worse than those that aren’t. In short, it’s not healthy for the plants in spite of their toxicity. The optimum solution is definitely by avoiding them altogether.
Before choosing amongst beautiful petals to get for a bouquet decoration, or to plant in your outdoor garden, you should first know the flowers that can cause hazard to your kitties. Do keep note, just because the plant in your garden is not in our list, doesn’t mean they’re not one of toxic plants for cats. For more details of all plants, ASPCA may be able to give you a more comprehensive description.

Signs Of Toxic Plants Poisoning On Cats
Different plants have different health risks to kitties, some a lot more dangerous compared to others; plants with more damage from insects or drought may have increased toxicity. Moreover, depending on their size and quantities of consumption, symptoms also vary with each individual cat. Having said that, symptoms of toxic plant poisoning in cats may range from light skin irritations to severe issues affecting the heart or kidneys.
Symptoms Of Poisoning In Cats
Firstly, symptoms of irritation include itchiness, scratching or licking, red, watery and/or dilated eyes, irritation around the mouth, swelling, or pale gums. Secondly, there are gastrointestinal symptoms such as vomiting or diarrhea. Remember, if they vomit hours after eating, many won’t connect their sickness to eating the toxic plants, so they are likely to keep eating it.
Above all, your cats can experience more dire symptoms like low body temperature, fever, depression, staggering (muscle weakness), hyper salivation (drooling), difficulties swallowing, breathing difficulties, irregular heartbeat, or frequent urination.
Visit the vet ASAP!
If you suspect your felines has ingested severely toxic plants as we highlighted, bring them to the vet immediately. Even if you have not seen your cats chewing on any, but notice them exhibiting any of the symptoms above, at least contact a veterinarian as soon as possible.
Do not wait for signs of ailments to show as by the time they do, it may be too late. If possible, bring along the plant itself or its part that have caused the poisoning for better identification and effective treatment.
Vets Now emphasizes that, unless a professional advises you to do so, never induce your cat to vomit. This may present more danger than leaving the toxin in their stomach. This is why it’s better to bring them to a vet as they will perform a safe exam and do the required blood test before diagnosis.
