Tessa is our first cat. We bought her, when she was 8 month old. She had been living among a lot of other cats - more than a hundred - so she had quite a few problems being alone. She was never real happy, so at last we decided to buy another cat for her.
We bought Tam-Tam (male), when he was 12 weeks old, and it changed Tessa's life. She loved him from the start. They slept together from the first night.
Now we have two cats - it's not more difficult - but it's much more fun....
