Some idiot vigilante tried to take the “wildlife“ of Cal Anderson park into their own hands and now I’m at the vet pic.twitter.com/c4sYuH4NhP — thot leader (@EvaGiselle) July 19, 2016

A Capitol Hill dog was sickened Tuesday after eating what appears to be rat poison left near the playground in Cal Anderson Park.

Eva Gisellse tells CHS she was walking her dog Data in the park around 6 PM on Monday when the blue heeler ate an unknown substance. After Data became sick Tuesday morning, Gisellse retrieved the green substance and took her dog to Urban Animal at Broadway and E Thomas.

An Urban Animal spokesperson told CHS the substance was almost certainly rat poison, but veterinarians are awaiting final test results for confirmation. Thankfully, Data is recovering in her Capitol Hill apartment.

“We recommend that anyone walking a dog in the area makes sure it does not eat anything off the ground,” said Jen Pohlman, operations manager at Urban Animal. Of course, the same goes for humans.

UPDATE (7/20): After being notified of the incident, Seattle Parks had its pest control contractor check the roughly 20 rat poison traps that were set around Cal Anderson Park earlier this year. According to Parks spokesperson Christina Hirsch, there was no evidence of tampering on the traps, which are designed to keep poison away from dogs and children. “All of the traps were locked and all of the traps have been regularly serviced,” she said.

Pohlman said Data is the first case Urban Animal has seen of a dog eating rat poison in park since the office opened four years ago.

“I’m glad I caught it in time, she should be fine,” Gisellse said. “I’ve heard that people are taking the rat problem at Cal Anderson into their own hands by putting down poison, but I don’t know who.”

UPDATE: A Seattle Parks spokesperson tells CHS a pest control contractor installed some 60 20 rat poison traps around Cal Anderson Park in February. Teal colored bait was locked inside the traps which are “designed in a way to prevent dogs from accessing the bait,” the spokesperson said. It is unclear if the poison ingested by Data came from the traps. The pest management company will be inspecting the bait stations Wednesday morning, according the parks official.

At least one dog died and others fell sick in Snohomish County from eating rat poison left in a park earlier this year. Snohomish County Animal Control investigated the death as an intentional poisoning.
