Plants hazardous for cats: catalogue

The Internet abounds with the lists of poisonous plants but they are often far from being complete. It is impossible to remember everything. So it’s easier for the cats owners to examine their own plants for hazards for cats health than try to remember the long lists of poisonous plants.

Far not all the plants which are mentioned in the lists of dangerous for cats herbs can cause serious poisonings. So you dont have to take all these lists so serious. But there are some deadly poisonous plants that every ailurophile has to know about.

Every ailurophile should also realize that it is better to be too careful that just careless: plants should be put aside of the cats way because most houseplants are poisonous in varying degrees.

Many garden and field herbs can cause cats poisonings of greater or lesser severity. Most cats owners are sure that as soon as they take their pet outdoor it can easily find some useful herbs on its own. It is not quite so. Cats navigate their search by smell and taste and they sometimes make mistakes. The mistake can sometimes cost them their lives: the plant can be treated with pesticides. Some gardeners throw everywhere in their garden rat poison. Those poisons arent perceived by cats as dangerous substances. Both cats and dogs often get poisoned and die.

Below you can find a list of the most common poisonous plants. Remember that many of plants which are mentioned here have a lot of sorts and varieties and different species of one plant (genus) can differ from each other markedly. The fact that plants on your windowsill are not similar to the plants in the pictures below does not mean that your plants arent poisonous. Find out the names of your houseplants and check them using the names (the 1st column) but not the pictures.
