Funny Cat

Human medicines should never be given to cats. For example, the painkiller paracetamol (also called acetaminophen, sold as Tylenol and Panadol) is extremely toxic to cats: even very small doses can be fatal and need immediate treatment. Even aspirin, which is sometimes used to treat arthritis in cats, is much more toxic to them than to humans and must be administered cautiously. Similarly, application of minoxidil (Rogaine) to the skin of cats, either accidentally or by well-meaning owners attempting to counter loss of fur, has sometimes been fatal. Essential oils can be toxic to cats and there have been reported cases of serious illnesses caused by tea tree oil, and tea tree oil-based flea treatments and shampoos.
Other common household substances that should be used with caution around cats include mothballs and other naphthalene products. Phenol-based products (Pine-Sol, Dettol (Lysol) or hexachlorophene) are often used for cleaning and disinfecting near cats' feeding areas or litter boxes but these can sometimes be fatal. Ethylene glycol, often used as an automotive antifreeze, is particularly appealing to cats, and as little as a teaspoonful can be fatal. Some human foods are toxic to cats; for example theobromine in chocolate can cause theobromine poisoning, although few cats will eat chocolate. Large amounts of onions or garlic are also poisonous to cats. Many houseplants are also dangerous, such as Philodendron species and the leaves of the Easter Lily, which can cause permanent and life-threatening kidney damage.
