For me one of the hard things is that the little habits we had together are gone, but very alive in my memory, and there will be a moment where I expect something to happen and then remember why it's not happening, and I feel very sad.
The OH left the door to the bedroom open when he got up, but she wasn't there when i woke up. (She used to come into the bedroom and wake me.)
She didn't come into the bathroom and go "meep?" when I got up to go to the bathroom.
She wasn't running in and out of the kitchen impatiently while I made my coffee. I didn't make her breakfast along with my coffee.
She didn't sharpen her claws on the cat condo and then jump up on it when I sat down at my computer.
My computer was asleep, because she didn't walk on the keyboard last night on her way to the bedroom.
