Flowers and plants
While they may be pretty, lilies are one of the most poisonous plants for cats. Petside suggests keeping them out of the house (or better yet, purchase artificial flowers). Be aware of symptoms of lily poisoning which include vomiting, lethargy, and loss of appetite. Call your vet as soon as possible if you think your pet has ingested lily. The American Society for the Prevention of Cruelty to Animals (ASPCA) says that without immediate care, cats who eat lily may develop life-threatening kidney failure within 36 to 72 hours of ingestion. (By the way, here are 50 secrets your pet wishes they could tell you.)
Holiday poinsettias are also dangerous for pets, though not as worrisome as the lily. This doesn’t mean your pet should eat this pretty red Christmas decoration, since doing so will likely lead to stomach pain and discomfort, including vomiting.
The ASPCA’s compiled a searchable plant database of dangerous plants (listing over 400 items). Check it out if you are considering bringing a new plant home.
Chocolate might have plenty of health benefits for humans, but it’s a harmful food for pets. Petside says most adults know this, but that it’s adults’ responsibility to make sure children know, too. Keep little ones from giving chocolate to pets and do your best to supervise.
All kinds of candy–including candy wrappers
Too much sugar can give your pet a bellyache, but worse, if wrappers are swallowed, your pet risks tearing of the esophagus or intestines. Clean up as best and frequently as you can when candy is being unwrapped.
More harmful foods
Your pets should also steer clear of chewing gum, grapes, raisins, macadamia nuts, avocados, onions, garlic, salt, raw yeast dough, and fatty foods. Here are some other foods that can be seriously hazardous to your pet.
