It's not as easy as it looks

This blog is the first sad story I've had to tell. You see, despite my happy-go-lucky life here at the veterinary clinic with my mom and dad, not everything that happens here is fun. Today was a perfect example of one of those days.
The morning started out as any other with dog and cat visits; lots of wagging tails and barking banter. Thankfully, we had completed our lunch trot around the building, making sure all the the right spots were appropriately scented, when the sick cat came in.
I know it was sick because he wasn't moving, or breathing, like any cat I had ever seen before. Instead of a normal cat voice, he had a low gurgle that seemed to bubble as he breathed. My mother and her team quickly surrounded him and soon, out came all the tubes and wires. The look on my mother's face was enough to tell me everything I needed to know. She was worried. What exactly what she was worried about I wasn't sure, but it's not often that I see her worried, so I knew it wasn't good.
Once all the machines were set up, the cats' breathing seemed to calm down, but then so did all the other parts of him. With each breath he seemed to be saying, "Rest, just rest". I don't think mother speaks cat any better than me because she did everything but rest. She kept looking first at the sick cat, then at some books, then at the machines and then back to the cat. Soon another cat arrived and red syrup was being taken out of one and then given to the other.
"Rest, just rest... just rest" was all that cat would say with each labored breath. Before long, that's just what he did. I heard his heart stop before mother did, and still the worried expression never left her face. I thought that she would have been happy that the cat got what he wanted. As she talked into the black button machine on the wall, I could see her sharing the story all over again.
It's weird that the cat was the sick one, but everyone else seemed to be feeling the pain.
That night at home the water came from mother's eyes, and I did my job and cleaned her face and let her hug me. Although I wish I could have done more to help her today, I know that my very presence that night was enough. After all, this is me we're talking about.
