The garden experts at BillyOh.com have warned that whilst flowers such as lilies, tulips and azaleas may look pretty, they are potentially deadly to cats, dogs and even horses.
Even tomatoes and potatoes can be dangerous if your furry friends eat them when green and unripe, though it is mainly the toxic leaves that can harm cats and dogs.

A spokesperson for BillyOh.com said: “Flowers can look gorgeous and smell even better, but many can be very dangerous to a beloved cat or dog.
“So, when you’re deciding which plants to put in your garden, or even a pot in the house, do check first to make sure it isn’t toxic to your pets.
“If your pet shows any sign of having ingested poison, such as vomiting, diarrhoea, weakness or confusion, seek veterinary assistance straight away.”
1 Azaleas

2 Foxtails
Foxtails are spikelets that carry the seeds of the foxtail grass. They are barbed and meant to burrow into the ground to germinate – but this also means they could penetrate an animal’s body instead and damage internal organs. The ears are especially vulnerable.
It’s pretty much impossible to avoid this common weed, but you can check your pet’s body (especially entry points like the ears, mouth and eyes) frequently, especially after a walk, and uproot – not mow – any foxtails you see in the garden.
3 Lilies
Every part of a lily is toxic to cats (even one leaf or petal can make them very ill) and some kinds are poisonous to dogs as well. They are even toxic to horses.
4 Tulips

5 Potatoes
Unripe, green or raw potatoes are dangerous to dogs, and the leaves are toxic too. If you must grow potatoes, make sure your pets can’t get at them.
6 Tomatoes
The leaves are toxic to cats and dogs, so either avoid growing them, or make sure that animals can’t get to them.
7 Castor Beans
Ricin is a well-known poison, and it’s present in the bean of the castor oil plant – although all parts of the plant are toxic. Even tiny amounts can poison a cat or a dog and cause twitching, tremours, seizures, comas or death.
8 Heavenly Bamboo

9 Autumn Crocus
Not to be confused with the spring crocus (which can still cause vomiting and diarrhoea), all parts of this plant are toxic. It can cause liver and kidney damage, seizures and death.
10 Sago Palm
These ornamental houseplants are very poisonous to cats and dogs. The whole of the plant is dangerous, but the nuts are the worst. If you think your pet may have ingested some, take it to a vet immediately.
