its really sad to hear all ur stories! but u shud keep pets! seeing them u can learn something called Unconditional Love. I have lost 2 dogs. One dalmation n 1 daschund. My daschund died in a car accident. she never left the gate n went out. god knows wat happnd 2 her tht nite. she dug the mud beneath the gate n went out. v were calln her name. she wasnt around. then my dad went out n looked out 4 her. a shopkeepr told him tht one dog was cryn as if it was hit by a car. my dad checkd again n found her lying in a corner. she cudnt move. the car incident happend half an hr befor. n she waited till my dad came 2 find her. The moment my dad saw her he ran 2 her, n she looked into my dad's eyes n passed away. This was the worst experience of my life. v cudnt come out of it. I had never seen my dad cryn. after few days he got us a new pup, the same breed! as days paased by, things got normal, n my new baby got loads of happiness in our life! V still remembr departed one in our prayers!

so i wud say that pets might get tears in ur eyes when they r in a critical stage. but no one can give u happiness like they do!
