A guide to the animals and plants we share the world with. Which ones can hurt you, which ones are secretly harmless, and how to look after the ones who live in your house.
Made by kids, for everybody. Every fact is looked up and sourced. If we cannot source it, it does not go on here.
Haley, Pippa, Ries, Madison and Stella are building this right now. Every one of these went live within about a minute of them asking for it.
If you only remember one thing from this whole page, make it this list. Every row comes from the ASPCA Animal Poison Control Center or the U.S. Food and Drug Administration.
| Food | Why it is dangerous |
|---|---|
| Chocolate | It has a chemical called methylxanthine that dogs cannot handle. Dark baking chocolate is the worst, white chocolate is the mildest. Yes, this is sad. No, they still cannot have any.[1] |
| Grapes and raisins | Even a small handful can shut down a dog's kidneys. It seems like the most harmless snack in the house, and it is one of the most dangerous.[1] |
| Xylitol | A sweetener hiding in gum, candy and some peanut butters. It crashes a dog's blood sugar and can hurt the liver in 12 to 24 hours. Always read the peanut butter jar before sharing.[1][2] |
| Onion, garlic, chives | They upset the stomach and can damage the red blood cells that carry oxygen around the body.[1] |
| Raw bread dough | This one is wild. Raw dough keeps rising inside a warm stomach and turns into alcohol while it is in there.[2] |
| Macadamia nuts | They make dogs wobbly and shaky. Nobody is completely sure why yet, which is a real thing scientists are still working on.[1] |
If somebody in your family has a cat, this is the most important plant fact on this page. The whole lily is dangerous to a cat. Not just the flower. The leaves, the pollen, and even the water in the vase. A cat can go into kidney failure in less than three days from a small amount, and it can be deadly without a vet.[3][4]
So if you have a cat, the easiest answer is just do not bring lilies into the house at all.[3] Getting flowers for somebody with a cat? Pick literally anything else. For any other plant you are unsure about, the ASPCA has a searchable list of what is safe and what is not.[5]
A cat can get lily pollen on its fur, lick it off while cleaning itself, and never actually eat the flower at all. That is what makes this one so sneaky.
Real guides for the pets people ask about the most.
A turtle can live for forty years. That is longer than most people keep a car. A turtle is a promise, not a phase.
Two male bettas cannot share a tank. Ever. They will fight. It is literally why they are called fighting fish.
Stuff everybody repeats. We went and looked it up, and some of it turned out to be completely made up.
Here is the math. A bald eagle only weighs about 10 to 12 pounds itself, and it can carry roughly a quarter to a third of that, so about 3 to 5 pounds. Almost no dog weighs less than that. Eagles are also very nervous around people, which is why wildlife scientists doubt most of these stories.[13]
The tiny bit of truth in it: a great horned owl can take something over five pounds. So a very small pet outside at sunrise or sunset is not impossible, just rare. If you are actually worried about your dog, worry about coyotes.[10]
This one is wrong twice in the same sentence, which is impressive. First, a harvestman is not even a spider. Second, it has no venom glands at all, so there is nothing for the fangs to deliver in the first place. The cellar spider, which people also call daddy long legs, does have a little venom, but it is nowhere near the most venomous anything.
Try this one on a grown-up. They will absolutely argue with you.
The rhyme tells a venomous coral snake apart from a harmless king snake, and Florida wildlife officials say the coral snake has the strongest venom of any snake in North America.[11] But the colors do not follow the rhyme in other countries, so it stops working the second you leave. The real rule is way simpler: never pick up a snake you cannot name. Even Florida's venomous ones leave you alone unless you step on them or bother them.[11]
Search for one by name, or pick a group. Danger is a number AND a color at the same time, so it reads the same way for everybody.
A venomous animal has a delivery system: fangs, a stinger, or a spine. It has to get the venom into you somehow. Snakes, spiders, scorpions, bees and jellyfish are all venomous.
Remember it: if it bites you, that is venomous.
A poisonous animal or plant only hurts you if you touch it or eat it. It has no way to attack. Poison dart frogs, pufferfish and poison ivy just sit there being poisonous, and none of them will ever chase anybody.
Remember it: if you bite it, that is poisonous.
Poison ivy and poison oak grow their leaves in little groups of three. Poison sumac is a cheater and has way more leaves, so honestly, if you cannot name a plant, just do not touch it.
It is silly and it is a little bit gross and it works every single time.
After a turtle, a lizard, a frog, or anything that came out of a tank. Reptiles carry Salmonella even when they look absolutely spotless.[7]
How we check things. Everything on this page comes from a government agency, a university, a veterinary group, or a wildlife organization. When sources disagreed about how dangerous something was, we went with treating the animal with more respect, not less. When we could not prove something, we either left it off or put it in the myths section. Grown-ups check every safety fact before it goes up.
This page is for learning. It is never a replacement for a veterinarian, a doctor, or poison control.
Mind of Animals was built by five kids over one weekend in August 2026. They picked the animals, argued about the danger ratings, wrote the memory rhymes, and checked the sources. Everything on this page exists because one of them asked for it.
Mind of Animals is made by the kids of the team behind Top Rated Vets.
We built it so people and animals can share the world without so many accidents. If we got something wrong, or you want us to add an animal, tell a grown-up on the team and we will go look it up properly.
