Glad to know you aren't a serial killer. I'm only saying that everyone should at least make the best possible effort to avoid killing strays.
I wish I was a vegetarian to save animals, though, all of my life I loved red meat. If I don't eat the nice, juicy, prime rib of beef, then someone else will.
We should all be thankful that we were not born as animals because life can be short or difficult.
Word of the day: Change that litterbox once a week and clean it well. Your cat will love you for it. Don't be lazy and just add some fresh litter to the old.
Keep your dogs head cool. On a hot day outside, he/she might like an ice pack for a little while.
