Doesnt matter, they're still life, and in that we shouldnt be holding grudges.
I was cycling through the park a bit back and came across a squirrel clinging to a tree, about 6' off the ground, staring intently at a dog. The dogs owner was standing there, and the dog was fixated at the squirrel with the same intensity the squirrel was paying to the dog, so it didnt see me.
I approached very slowly until i was standing by the tree about 2' from the squirrel, who was too engrossed to notice me, and could have reached out and touched it. It was a fantastic sight, mother nature in its finery.It then got a sense I was there and scampered up the tree.
I remarked to the old guy with the dog how amazing it was to see a squirrel that close.
He like a total prick muttered something about killing it, and shame his dog hadn't caught it.
Although this was a lie and i like dogs, i told him forcefully that i didnt really like dogs and would he like it if i killed his dog.
He put the dog on its lead and quickly hurried away.
No need for that in my opinion. Animal is an animal. Right to life and all that.
