Well, IF Lily does't really make it to the outside one day, there's no danger she could get pregnant.

However I have spoken to my vet today and she thinks these could very well be first signs of the heat, and she will get pills now to control the effects. As soon as she's done with the first heat, she'll be spayed.

I find it interesting to hear that some cats here have obviously been spayed at a very young age. Here in Germany, they usually don't do it before a cat is at least 6 months old. Lily is 5 months and 10 days now.
