It is true. I would not trade the 7 years of happiness and love I had with Theo even though losing him so suddenly hurts so much now. I just wish I could know with certainty there was nothing I could have done to change the outcome. He was so full of love. If I failed him in any way how could I ever forgive myself. He was over due for his annual exam. What if they would have heard a slight heart murmur or other subtle sign something was wrong? Maybe he would still be here? He was so lively and seemingly healthy, I kept telling myself, "I need to take him in for that check up..." but everything else seemed more pressing...guilt and regret. What if, what if. The vet does not even know for certain it was heart failure...only maybe. His heart looks perfect. Not knowing is so awful. It will be weeks until the final report is in. And it still may not tell me why. My baby....i've cried at least 4 times today. Trying to give my other kitty extra love. But, having another cat does not take away the saddness of losing Theo. My house actually feels cold and empty. All the annoying things he did...like putting his paw in every glass of water you turned your back on for one second, throwing everything off the kitchen island until you gave him his dinner and opening cabinets to get inside and poke holes in the cat food bag to get a treat...wow...what I would not give to drink paw water one more time.
