I Spent Most of My Birthday in Prison

I was settling in to enjoy my birthday. We had a game with my tunnel in the loungeroom and I allowed Lynettea to brush my furs for a short time.
We went for a walkies, as it was cool and pleasant in the garden.
Then I had another helping of my favourite jelly food and leaped on the washing machine.  I was turning around in my cosy preparing for my morning nap, when I heard strangers at the door.
'It is your guests, Sasha, for your birthday treat,' said Lynettea.
I bolted into the bedroom and into my underbed cosy, where I feel safe.
The three visitors were not my friends. They were Lynettea's friends from the gym. One of them asked where I was, but after that they chatted and did not try to find me. Lynettea told them it was my birthday and I was resting.
After they left, Lynettea decided to change the water in the fishpond and do some gardening, so she shut my door, trapping me in the front of the house. It was as if I were in prison.
'But Sasha, you still haven't come out!"
She is trying to fob me off.
'I will come out when I feel like it.'
I hope the rest of my birthday is better.
