Which plants are poisonous to dogs and cats, which are safer to keep, and what to do if your pet has been near a lily. Advice from Avonvale Vets in Warwickshire.
As spring and summer arrive, homes and gardens fill with colour. While plants and flowers brighten up living spaces, they can also pose hidden risks for pets. Both cats and dogs are naturally curious and may chew, lick or brush against plants, sometimes with serious health consequences.
Knowing which plants are safe and which are toxic is an important part of responsible pet ownership. This guide explains what cat and dog owners should look out for, and how the team at Avonvale Vets can help.
Why plants can be dangerous for pets
Pets interact with plants in different ways.
- Dogs may chew plants while playing or exploring
- Cats may nibble leaves, pollen or flowers out of curiosity
- Pets can absorb toxins through the mouth or skin
- Even small amounts of some plants can be harmful
Risks increase in spring and summer because more plants are indoors, gardens are in full growth, and pets spend more time outside.
Garden plants that are toxic to cats and dogs
Many popular garden plants can cause illness if eaten.
Plants to be cautious of include
- Lilies which are extremely dangerous for cats
- Daffodils
- Tulips
- Foxglove
- Bluebells
- Azaleas and rhododendrons
- Ivy
- Lupins
Some plants may affect dogs and cats differently, but all should be treated with care. Locally we tend to see the most issues from Giant Hogweed.
Why lilies need their own warning for cat owners
The risk from lilies is much greater than most people realise, and it is worth a few extra lines.
All true lilies (Lilium species) and day lilies (Hemerocallis species) are highly toxic to cats. Every part of the plant is dangerous, including the petals, leaves, stems, pollen and even the water from a vase. A cat brushing past a flower and then grooming the pollen off its fur can be enough to cause harm.
The main risk is acute kidney injury, which can develop within one to three days and is often fatal without urgent veterinary treatment. If you suspect your cat has had any contact with a lily, contact your vet immediately. Time really matters here, so please do not wait to see if symptoms develop. Out of hours, call 01926 400255.
The safest approach is simply not to bring true lilies or day lilies into a home with cats, and to avoid them in cat-accessible parts of the garden.
Common houseplants that can be harmful
Indoor plants are a frequent cause of pet poisoning. If you're after pet safe houseplants, some are well worth swapping in.
Plants to avoid include
- Peace lilies
- Aloe vera
- Snake plant
- Dieffenbachia
- Monstera
- Philodendron
- Jade plant
Dogs may chew leaves, while cats may be affected by pollen or sap. Hanging plants can reduce risk, but removal is often the safest option.
Pet safe plant options
There are plenty of plants that are considered safer for homes with pets.
Pet friendly choices include
- Spider plants
- Areca palm
- Boston fern
- Calathea
- Herbs such as basil, rosemary and thyme
- Cat grass and catnip for cats
Even safe plants can cause mild stomach upset if eaten in large amounts, so discourage excessive chewing where possible.
Other outdoor hazards to be aware of
Plants are not the only spring and summer risks in gardens.
Watch out for
- Slug pellets and pesticides
- Weed killers and fertilisers
- Blue green algae in ponds
- Compost heaps and garden waste
Pets can walk through treated areas and ingest toxins while grooming, so always store chemicals securely.
Signs of plant poisoning in cats and dogs
Symptoms can vary depending on the plant and the pet.
Look out for
- Drooling or foaming at the mouth
- Vomiting or diarrhoea
- Lethargy or weakness
- Loss of appetite
- Tremors or seizures
- Difficulty breathing
If you notice any of these signs or suspect your pet has eaten a toxic plant, contact Avonvale Vets on 01926 400255 immediately.
