I'm going to miss my big guy so much

Oscar died today.
I'm heartbroken.



It was very unexpected. He seemed fine this morning, cuddled with me, played with Ward for a bit. The regular routine.
Then, around 1:00 p.m., I walked into the den and saw him laying on the floor. I called his name and he didn't respond. I moved some of the stuff around him out of the way (he had laid down among some boxes and stuff) and called him again and he still didn't respond. So, I tried to nudge him, bc I was getting scared. And that's when I realized my big, fluffy guy was gone.
I'm so sad. I can't seem to stop crying. I miss him so much. He has been with me since I was 21. He slept with me every night and greeted me every day I came home from work. He even took care of me in his weird kitty way when I was hurt after my car accident by laying with me bc he knew I didn't feel good.
He was a wonderful cat. He definitely had his own funny, silly, cute personality. He managed to charm everyone who met him, even people who said they didn't like cats. Oscar always seemed to be able to convince them otherwise.
I'm going to miss him so very much. And poor Ward lost his best bud and snuggle friend. He is pretty confused about where his friend is and why he isn't coming out of hiding to play with him.
I love you, Oscar. You'll always be my big grumpy guy. I hope wherever you are, you have all the cardboard boxes your heart desires  and all the fishy treats you  can eat. I miss you, big kitty.
