Spring's dangers come up out of the ground: bulbs, slug pellets, fresh fertiliser, waking ticks - plus the Easter shelf and one flower that is genuinely deadly to cats.
Read this first. This page is a reading checklist, not veterinary advice - we do not give treatment steps or doses, and nothing here replaces a professional. If your pet may have eaten or touched any of these, call your vet or a poison line now, with the packet, plant or product name if you can.

Lilies - the cat emergency
Easter and spring bouquets. True lilies (Lilium) and daylilies (Hemerocallis) are catastrophically toxic to cats - petals, leaves, pollen and even the vase water.
Signs: Vomiting, drooling or lethargy in the first hours after contact - but kidney damage is already under way before the signs look serious.
What to do: Any suspected lily contact in a cat - including pollen dusted on fur - is an immediate emergency trip. Treated early, the outlook is good; treated late, it often is not.
Prevention: Cat households should simply never contain lilies. Check bouquets before they come inside; 'spring mix' very often includes them.
Easter chocolate, raisins and sweets
Egg hunts leave chocolate at nose height, hot cross buns carry raisins and sultanas, and sugar-free sweets can carry xylitol.
Signs: Chocolate: vomiting, restlessness, racing heart. Grapes and raisins: sometimes only vomiting at first, with kidney injury following. Xylitol: weakness, collapse, seizures.
What to do: Call your vet or a poison line at once with the wrapper or recipe in hand. With raisins and xylitol, do not wait to see how it goes.
Prevention: If children hide eggs, count them and collect the leftovers before the dog does. Keep baking days and dogs in separate rooms.
Spring bulbs
Daffodils, tulips and hyacinths - in the border, in planters, and in bags waiting to be planted. The bulb is the most toxic part, and digging dogs go straight for it.
Signs: Drooling, vomiting, stomach pain, wobbliness; daffodils in quantity can affect heart rhythm.
What to do: Call your vet with the plant name and how much was chewed or dug up.
Prevention: Store bulb bags like chemicals - shut away. Fence off freshly planted beds; dogs smell the disturbed earth.
Fertilisers, compost and cocoa mulch
Fresh-fed lawns and borders. Bone meal and blood meal smell like dinner to a dog, cocoa-shell mulch is chocolate's cousin, and mouldy compost carries tremor-causing toxins.
Signs: Vomiting and diarrhoea after grazing a treated bed; fine muscle tremors that grow after raiding compost; iron-rich products can be more serious.
What to do: Call your vet with the product bag or a photo of its label - the ingredient list changes the answer completely.
Prevention: Water fertiliser in and keep pets off the lawn per the label. Choose plain wood mulch over cocoa shell. Keep the compost bin latched.
Slug and snail pellets (metaldehyde)
Scattered blue-green pellets in beds and greenhouses - among the most dangerous things a dog can find in a garden.
Signs: Anxiety and twitching escalating to tremors and seizures, often fast.
What to do: This is an immediate emergency - go now, bring the packet. There is no safe wait-and-see window.
Prevention: Do not use metaldehyde pellets in a pet garden at all. Iron (ferric) phosphate pellets are less hazardous but not harmless: the National Pesticide Information Center at Oregon State University notes that dogs have become ill after eating them, so store the pack out of reach and scatter the granules thinly, never in piles.
The wrong parasite product
Spring is deworming and flea-treatment season - and a dog spot-on containing permethrin applied to a cat is a genuine poisoning, not a mix-up.
Signs: A treated cat that starts twitching, trembling, drooling or seizing - sometimes hours later, sometimes after grooming a freshly treated dog.
What to do: Emergency clinic immediately, packet in hand. Wash-off and treatment work far better early.
Prevention: Read the species and weight line every single time, never split large-dog pipettes, and keep a treated dog away from cats until the application site is dry.
Bees, wasps and first stings
Pets snap at the first buzzing things of the year - so most stings are in the mouth or on the face.
Signs: Sudden yelp, pawing at the face, local swelling. The worrying version: swelling of the muzzle or throat, laboured breathing, weakness, collapse.
What to do: A simple paw sting can just be watched, but face or mouth swelling, breathing trouble or collapse is an emergency - go straight in.
Prevention: Discourage fly-snapping games, and check clover patches before letting a barefooted dog charge in.
Ticks waking up
Tall grass, brambles, deer paths - tick season starts the moment the ground warms - and after a mild winter it barely stops at all.
Signs: The bite itself is silent. Tick-borne disease shows up weeks later as lameness that shifts legs, fever, lethargy or loss of appetite.
What to do: Remove ticks promptly with a twister tool (no burning, no smothering), note the date, and see your vet if your pet is off-colour in the following weeks - mention the tick.
Prevention: Ask your vet which preventive suits your pet and your region, and make a tick check part of the after-walk routine from March onward.
This checklist is general awareness information drawn from widely accepted veterinary and poison-control guidance. It is not a diagnosis, a treatment plan or a substitute for professional care, and risks vary with your individual pet, dose and region. In any suspected poisoning or emergency, your first move is to contact a vet or an animal poison line - not to search further.
