Yarrow was put to sleep on 17 April, 2008, the day before I flew to New York for a much-needed week-long break, spent with my friends.
That week was able to distract me, more or less, from missing Yarrow, but it wasn’t able to distract me entirely, and now that I’ve been home a week and his remains have been delivered from the crematory service I send all my ratties to, the box is now resting in one of his favourite spots next to my window.
Yarrow was only just over a year old. From the time he was very young I had always noticed that he breathed a little too rapidly, a little too heavily. I knew it was a congenital defect, a growth - something that would never be able to be cured, only handled and maintained until it grew too severe for him to cope with. I hoped that he would be able to live longer than he did, and tried to give him the best life that I could while I had him. When he really began showing signs of distress in the beginning of March of this year, I took him in to verify what I had suspected all along: Yarrow had a massive growth in his lung. The tumour was so large it was literally squeezing the breath out of him; it took up nearly his entire chest cavity and not only inhibited his lungs but pressed against his windpipe. It was only a matter of time before this tumour suffocated him to death.
When I got him, he grew to be a very, very special rat to me. All my rats are special to me, but Yarrow was one of the different ones. He was mischievous and very, very smart, and full of fun. He was a practical joker. He used to play pranks on me all the time; he’d invent games, he’d play tricks on the other rats - and whenever he was up to his shenanigans he’d have an expression on his face that made him look EXACTLY like Harpo Marx. He used to sit and stare at me with that little masked face of his, and as he began to decline his eyes would never leave me. He rarely left my side, because I always knew I wouldnt have much time with him, but toward the end he was literally with me night and day.
The vet was very kind. He gave me steroids to inhibit the growth of the tumour as long as possible. My rat guru gave me a lot of support and advice and wholeheartedly and without hesitation offered to care for him while I was in New York.
The trip to New York was tormenting me. How could I leave him? Even with my rat guru, who knows more about these creatures than any human being I have ever met, it was not the same as me being here. He counted on me; he’d start to panic if I wasn’t around. How could I go off to New York and have a good time just at the time he needed me most? For the first time in my entire life, I hated - really hated - the idea of going on a trip. For the first time, I hated having to go to New York.
The weekend before I was set to leave, Yarrow worsened. A day or two later, I knew there was pretty much nothing more that could be done for him. I waited, spending as much time with him as I could, and that Tuesday night, he began to show the first real signs of being unable to breathe. Wednesday, he grew worse and started having his first gasping episodes. He was eating, he wanted to play, he wanted to cuddle, he was a normal, healthy rat in every way - except that he had an alien in his chest that was squeezing the life out of him with each passing moment, and now he was suffering.
I put Yarrow to sleep on Thursday morning. He died easily, surrounded by love and familiarity, not strangers or a cold examination room being handled by people who he did not know. He simply went to sleep. He wanted to live. I wanted him to live. But there was nothing either one of us could do, and letting him die a death of slow suffocation was simply not an option. I wasn’t feeling guilty; just heartbroken.
The cruel irony of it all is that one thing Yarrow used to particularly enjoy was smelling the air. From when I first got him, every time a breeze would blow in through the window, he’d raise his head and sniff and sniff and sniff and sniff. He’d lie in front of the window by the hour, sleep in front of the window. He loved to breathe. I gave him all the air I possibly could for as long as I possibly could.
Well, this is a testament to my boy. I love my other rats completely, and I am trying hard not to neglect them, but I miss Yarrow very, very much. So now what is left of his physical form sits in a handsome box in his old spot in front of the window. He may not be able to breathe the air anymore, but still it surrounds him, and true to my word, I will never abandon him. He’ll be with me always, just like all my other rats will. I just wish that things could have been different.
Safe journeys, Yarrow, my shining little masked prankster. Thank you for coming my way.
