can hamper their existence. Plants that are in the wild cause more harm to animals than those cultivated at home. If you have pets at home, ensure that you are aware of what type of plants you grow in your garden. Most of us are fond of our cats  and it is our responsibility to make sure we keep them safe. Instinctively, these felines are cautious of what they come in contact with, especially what they eat, but there may be circumstances that the cat may come into contact with harmful leaves or seeds. 

Kittens are more vulnerable to sampling plants as they don’t have the instincts of an adult cat.

Cats in the wild do not have the tendency to eat unfamiliar plants, but house cats have to be kept away from dangerous plants.

A common problem that cat owners face is their cats using and damaging their furniture. Instead of training their cats to not damage their furniture, some of them start putting them in the garden where they won’t destroy their furniture.

How to protect cats from poisonous plants?

The first step is to remove all toxic plants for cats from your garden and keep your cats indoor. Of course, if your cat is a free roaming one, then it is more difficult to prevent contact with toxic plants. If your neighbors have any potential toxic plants, then make a note of them, so that it will be easier for the vet to treat your cat. While buying plants from the nursery ensure that they are coded by the Horticultural Trade Association. Plants can be grouped into

Sometimes, any contact with leaves, stems and sap can cause skin irritation and rashes. In cats, it can cause itching and blistering of the mouth. Even leaves of tomato, carrot, celery, cucumbers and strawberry may cause skin irritation in cats. If you grow vegetables or ornamental flowers in your garden, it is ideal to restrict access of the cat to them.

Preventing free roaming of kittens in bushes when they are young is very important. Kittens are not very smart at recognizing any plants that may be allergic or toxic to them. If you take your kittens on a trip, make sure they don’t wander off in the bushes. Be aware of and keep an eye out for any toxic plants in the vicinity.

Immediate veterinary care

Only a veterinarian can confirm if your cat has been poisoned. If you notice strange behavior in cats or if it shows skin irritation, continuous vomiting or if your cat collapses it is time to approach a veterinarian. If you can get the

sample of the plant that you suspect, take it along with you to the vet. This can help the vet to get an antidote quickly to save your cat from discomfort. Sometimes it may take a long time for the poison to work on the cat so it is wise to always keep a watch on your pet.

The vet gives the cat activated charcoal to absorb the toxins from the gut and also give medication like sucralfate to heal the damages in the stomach.

Cats are prone to probing and it is difficult to control their wandering nature due to their climbing traits. As responsible pet owners, you have to take care of your pet and ensure that they are properly fed and watered. Make a note of the plants in your garden and if you find any plants that can harm your cat, remove them immediately.
