Greymalk, would you consider a cat from a shelter?
Two near to you are Tierschutz Beider Basel: www.tbb.ch
And Tierschutzbund Basel: http://www.tierschutzbund.ch
Both have many cats needing homes.
You can also browse the Switzerland-wide database of homeless animals, here: http://www.tierdatenbank.ch/cms/tier...unschtier.html
You can filter by several criteria, such as location, age, sex, etc.
All the best as you search for your new friend.
