Why avocado is harmful to pets
Avocado contains a toxin called persin which can affect the heart and gastrointestinal tract of dogs and cats.
The fruit flesh may cause vomiting, diarrhea and abdominal pain, while the pit can cause an intestinal blockage.
Why speed matters
Delaying care significantly worsens outcomes. Some signs appear hours or days later, so "looks fine right now" is not a reason to wait.
