[Regarding “Seattle Arts & Lectures presents ‘Thinking Animals,” Dec. 31:] Animals have instincts; they don’t think.

I have five large dogs that moved into my property. I got them fixed and shots. Three of them were adults, and two were one female’s puppies. Since they grew up on the streets, they are like a pack. They kill anything that comes on the property.
