Is a sweetheart hoya safe for cats and dogs?
Hoya kerrii · Flowering houseplant
Non-toxic to cats and dogs
Hoya kerrii is confirmed by species, so the single heart-shaped leaf sold every February is fine on a table a cat uses as a walkway.
Source: ASPCA Toxic and Non-Toxic Plants.
It is. Hoya kerrii appears on the ASPCA's non-toxic list for both cats and dogs, which makes the heart in a pot one of the few gift plants that needs no checking before it goes on the table. The gift plants it sits among are less straightforward, poinsettia included, which the catalogue records as toxic at mild severity for cats and dogs. What the label rarely mentions is that a single rooted leaf with no piece of stem attached will often stay exactly the size it arrived.
Worth knowing anyway
Nothing here poisons a cat or a dog, though non-toxic and edible are not the same thing, and vomiting that repeats after a chewing session is worth a call to your vet or an animal poison line. Gift versions often arrive with moss or glued gravel dressing the top of the pot, and that, rather than the plant itself, is what a bored cat tends to pull out and carry off.
Living with one
A rooted heart is happy on a desk or a shelf a dog's tail cannot reach, and it asks for very little: the catalogue schedules it around every fourteen days, and it copes with being forgotten far better than with a weekly top-up. If you want the vining version rather than an ornament, look for a cutting that includes a piece of stem, because a leaf on its own has no growing point.

Questions people actually ask
Will a single heart leaf ever grow into a vine?
Usually not. A leaf will root and can live for years, but the bud that produces new growth sits on the stem, so a leaf taken without a piece of stem has nothing to grow from. Sellers rarely mention it, because the leaf looks perfectly healthy either way. If you want a plant that climbs, look for one with a node or a short length of stem visible at the base.
Which Valentine's plants are unsafe for cats?
The cut lilies in a bouquet are the serious one. The catalogue records Easter lily and stargazer lily as toxic at severe level for cats, with the effect on dogs recorded as unknown, and severe means calling a vet or an animal poison line straight away rather than watching what happens. Poinsettia sits on the toxic list at mild severity and cyclamen at severe, so neither belongs on a table a cat uses.
How often does a sweetheart hoya need watering?
Less than almost anything else on the windowsill. The catalogue puts it on roughly a fourteen day cycle and eases off in winter, because the leaf carries its own water supply. Rot is what kills these rather than drought, and a leaf gone soft and yellow at the base has usually been watered on whatever schedule suited the rest of the shelf.
Can the app tell one hoya from another in a photo?
It identifies a plant from a photo and builds a care schedule from there. A kerrii read as a wax plant does not change the safety answer, because both species appear on the ASPCA's non-toxic list. The watering is what shifts, since the two are scheduled differently, so it is worth checking which species it picked before you leave the schedule running.
