Is a Venus flytrap safe for cats and dogs?
Dionaea muscipula
Non-toxic to cats and dogs
Dionaea muscipula is confirmed by species. It catches flies rather than fingers, and there is nothing in it that poisons a cat or a dog.
Source: ASPCA Toxic and Non-Toxic Plants.
Nothing to worry about here. Dionaea muscipula appears on the ASPCA's non-toxic list for both cats and dogs, and the traps that make people nervous are a few centimetres long and shut on insects. A cat that sets one off gets a surprise and the plant loses a trap, since each one closes only a limited number of times before it blackens. The real problem with a flytrap in a house is not the animal. It is the tap.
Worth knowing anyway
Non-toxic and edible are different statements. A dog that chews the crown is more likely to be sick from the plant matter than harmed by it, and vomiting that carries on needs a vet rather than patience. The pot is worth a thought too: flytraps grow in a very acidic mix with no fertiliser in it, and a dog that digs one out has spread wet compost across the room and killed a plant in the same minute.
Living with one
A flytrap wants the sunniest windowsill in the house, which is rarely where you would put an ornament, so it ends up somewhere a cat can reach. That is fine. What is not fine is tap water: these are watered with rainwater or distilled water, standing in a shallow tray of it, and the catalogue schedules that around every three days, easing off as the light goes in winter. Full sun, and nothing out of a plant food bottle.

Questions people actually ask
Can a Venus flytrap hurt a cat's paw or a dog's nose?
No. The traps are small and built to hold an insect, and Dionaea muscipula is on the ASPCA non-toxic list for cats and dogs, so a nipped nose is not a poisoning either. What actually happens is that the trap shuts, the animal pulls away, and the trap has spent a closure it does not get back. Each one has only so many in it before it blackens and the plant grows a replacement.
Why is my Venus flytrap turning black?
Individual traps blacken after they have caught something or been triggered a few times, and the plant grows new ones. A whole plant going black is usually tap water. Minerals build up in a compost the catalogue keeps at pH 4.5 to 5.5, and they do not wash out again. Rainwater or distilled water only, full sun, and less water through winter, which the seasonal schedule already assumes.
Is a flytrap a good present for a house with a cat?
On safety, yes: it is on the non-toxic list for cats and dogs, and there is nothing to keep out of reach. On upkeep, be honest with whoever gets it. Full sun, rainwater and water every few days is more attention than a novelty plant usually receives. If you want the same appeal with less admin, a spider plant is on the list too, while the lucky bamboo often bought for that shelf is Dracaena sanderiana, recorded as toxic at mild severity.
Can someone else water it while I am away?
That is what the sitter link is for. Households sync over iCloud, and when you travel you can hand someone a link showing what needs doing without giving them the rest of your account. A plant on a three day schedule is exactly the case where that matters, since a fortnight away is the usual way a flytrap dies. Whatever the sitter logs stays in the plant's history.
