I agree with the poem completely ... I never see stray pets near my house because no-one near me would ever buy a pet without wanting to keep it but, when I went shopping last month, I saw a critically ill dog outside the shops and people where just ignoring it and walking by without giving it a second thought. I made sure it got to the local animal shelter though.
Also, I once saw an ill bird (It had also lost a wing when a cat attacked it) that I took to the vets strate away.
I've had 2 dogs before and both where from an addoption center.
