I lost my cat Jack, about 3 months ago...he was 21 yrs old!...a great little dude too!....never hissed or spat...he was just so laid back!..he was a champ!
I understand how people feel, about losing an animal...and I feel what you feel about not wanting to go through the pain of losing them...but I beg you to reconsider!
There are so many Dogs and Cats in shelters...just praying and hoping for a loving home!...I know it hurts...but the fact you have lost an animal you loved dearly, has made you who you are!...it is selfish to consider ones own feelings, when you may be in a position, to rehome a cat or dog who needs you!...would you not marry the person you love, or have children, merely because you may lose them someday?
Please...reconsider
