The not knowing WHEN is the hardest decision.... well, making the decision is the roughest decision... (you know what I mean)!!!! AND like everybody says... you'll know when its time. Sometimes the right time is when you just can't do it anymore. Like people... as an animal ages... their quality of life just isn't what it used to be... its hard on the person/animal. BUT when the animal is still doing their normal routine... and still quite pearky... is when we start second quessing ourselves. (meaning... second guessing the hard decision of when).
I know this well... for months I watched my princess get worse.... each night she would scream at the top of her lungs... just to wake me up. She couldn't jump up on anything... and she had a little limp... gained a lot of weight. But the vet said she was fine... just old.
I should have know better. She was telling me something... but I couldn't understand MEOWWWW.... I thought she was just meowing loudly as to get my attention no matter the day or night.
This went on for a year.... the vet still saying she was just old.... until one night... she just couldn't walk anymore. Obviously I knew our time together was over.
Did I wait tooooo long? Was she trying to MEOW/scream at me... letting me know.... all the while she was doing her same routine.... I know I was blinded by her beauty and her unconditional love. I just wouldn't believe that this or that... was the day.
OK back on topic.... YOU WILL KNOW WHEN ITS TIME!!!!!!! YOU WILL DEFINITELY KNOW!!!!!
My heart aches for you and my prayers are yours during this time!!!!!!!!
