Pet-Safe Spring Gardening Tips

With a little planning, creating a beautiful garden that is also pet-safe is doable, writes emergency veterinarian Denise Petryk, who provides a list of toxic plants and dangerous fertilizers and chemicals. Younger animals will eat anything and are at higher risk for toxicity, but even exposure to small amounts of some toxic garden components can be harmful to pets, Dr. Petryk warns.

AVOID the 10 most dangerous, most toxic plants:

— Castor bean (Ricinus communis) — oral irritation, vomiting, diarrhea, kidney failure, convulsions, death.

– Foxglove (Digitalis purpurea), pictured right – vomiting, diarrhea, weakness, cardiac failure, death.

– Japanese Yew (Taxus cuspidata) — tremors, difficulty breathing, vomiting, seizures, death.

– Jerusalem cherry (Solanum pseudocapsicum) — vomiting, seizures, depression, trouble breathing.

– Lily of the Valley (Convallaria majalis) — vomiting, heart trouble, disorientation, coma, seizures.

– Lily (Lilium species) — kidney failure in cats — ALL parts of the plant, even in small amounts.

– Morning Glory (Ipomea sp.) – vomiting, diarrhea, agitation, tremors, disorientation, ataxia, anorexia.

– Nightshade (Atropa belladonna) — drooling, vomiting, diarrhea, depression, slow heart, weakness.

The non-plant concerns in the spring include fertilizers, pesticides, slug bait, mulch, and garden tools. Talk to your local nursery about the safest options, read labels carefully and store everything safely in sealed containers or out of reach.

Try natural products like vinegar for weeds, coffee grounds, beer and salt for slugs, and soap and water as a natural pesticide.

Avoid cocoa mulch as it comes from chocolate manufacturing and can contain substances that will cause minor chocolate poisoning (vomiting, diarrhea, hyperactivity) as well as general irritation to the mouth, stomach and intestines.

Many of our mature dogs (and almost all of our cats) are discriminate — they might sniff but they are not inclined to eat plants.

Grass is often the exception and in small amounts, common grasses are safe. Ornamental grasses can be very irritating to the mouth, throat, and nose so if you have a big grass eater, it is safest to avoid these plants.

Remember that puppies and kittens are always an exception. They will generally eat ANYTHING! It still makes most sense however to always pick the safest plants possible for our spring flower gardens and our deck pots.

Horticulturists employed at our favorite plant nurseries are excellent resources for pet safe plants and gardening products. The ASPCA Animal Poison Control Center has a fantastic guide to pet-safe gardening and a wonderful collection of plant pictures and toxicity information here . PetPlace.com also has an array of informative articles written by veterinarians about toxic plants and gardening.

The three most common spring garden problems we see in our busy Tacoma pet emergency room include dogs ingesting SLUG bait poison (metaldehyde), dogs ingesting decomposing things out of the compost pile, and Lily ingestion or sniffing by cats.

A few bites of slug bait can cause horrible tremors. Quick emergency treatment is critical.

A compost pile snack can also cause tremors or it may cause drunk-like behavior or vomiting and diarrhea. Here too, quick emergency treatment is essential for a quick recovery.

Lilies are highly toxic to cats. It is safest to avoid all lilies — both as cut flowers as part of a bouquet or as a garden plant. Potential sniffing of the flower and inhaling the pollen can even be a problem to our cats.

Enjoy your garden but do your research first. Prevention is so much easier than sick animals and treatment.
