## Lilies

From wikipedia: Lilium

Some *Lilium* species are toxic to cats. This is known to be so especially for *Lilium longiflorum* though other *Lilium* and the unrelated *Hemerocallis* can also cause the same symptoms. The true mechanism of toxicity is undetermined, but it involves damage to the renal tubular epithelium (composing the substance of the kidney and secreting, collecting, and conducting urine), which can cause acute kidney failure. Veterinary help should be sought, as a matter of urgency, for any cat that is suspected of eating any part of a lily – including licking pollen that may have brushed onto its coat.

## Chocolate

From wikipedia: Health effects of chocolate

Main articles: Theobromine poisoning
In sufficient amounts, the theobromine found in chocolate is toxic to animals such as cats, dogs, horses, parrots, and small rodents because they are unable to metabolise the chemical effectively. If animals are fed chocolate, the theobromine may remain in the circulation for up to 20 hours, possibly causing epileptic seizures, heart attacks, internal bleeding, and eventually death. Medical treatment performed by a veterinarian involves inducing vomiting within two hours of ingestion and administration of benzodiazepines or barbiturates for seizures, antiarrhythmics for heart arrhythmias, and fluid diuresis.

A typical 20-kilogram (44 lb) dog will normally experience great intestinal distress after eating less than 240 grams (8.5 oz) of dark chocolate, but will not necessarily experience bradycardia or tachycardia unless it eats at least a half a kilogram (1.1 lb) of milk chocolate. Dark chocolate has 2 to 5 times more theobromine and thus is more dangerous to dogs. According to the Merck Veterinary Manual, approximately 1.3  grams of baker's chocolate per kilogram of a dog's body weight (0.02  oz/lb) is sufficient to cause symptoms of toxicity. For example, a typical 25-gram (0.88 oz) baker's chocolate bar would be enough to bring about symptoms in a 20-kilogram (44 lb) dog. Of course, baking chocolate is rarely consumed directly due to its unpleasant taste, but other dark chocolates' canine toxicities may be extrapolated based on this figure. Given access, dogs frequently consume chocolate at toxic levels because they like the taste of chocolate products and are capable of finding and eating quantities much larger than typical human servings. There are reports that mulch made from cacao bean shells is dangerous to dogs and livestock.

### Xylitol

In dogs, 100 mg of xylitol per kg of body weight (mg/kg bw) causes a dose-dependent insulin release that can result in hypoglycemia, which can be life-threatening. Hypoglycemia associated symptoms of xylitol toxicity may arise as quickly as 30 to 60 minutes after ingestion. Vomiting is a common first symptom. It can be followed by tiredness and ataxia. At doses above 500 mg/kg bw, liver failure is likely and may result in coagulopathies like disseminated intravascular coagulation.

Xylitol is safe for cats, which tolerate even 1000 mg/kg bw ingested doses of it. It is also safe for rhesus macaques, horses and rats.
