Lut,

I am so sorry to hear Zazou has wandered off again. I pray she is safe and will find her way home soon.

Also, I have to agree that it may be time to harness/leash train her. Warning it may take time and a lot of patience but it will be worth the effort

Eve was most definitely a wanderer her previous guardians would sometimes not see her for weeks at a time That changed when she landed on my doorstep At first she was reluctant as most cats are but soon learned that if she wanted outdoor time she had to compromise and eventually it became easier and easier. She now often goes out without a leash generally when we are outdoors and can keep an eye on her. Rarely does she stray and if she does wander off next door will come when she's called. This did not happen quickly .... and there were days when my hair could not have gotten any grayer, believe me!

The best option would be an enclosure however, training her on a leash will give you more flexibility if you travel with Zazou.

My heart breaks for you and I hope this can soon be resolved.

Hugs, Betty
