Actually they steal them, I had a Siamese stray and he also disappeared, I am sure they re-sell them at Souk Wagif, I am sorry to say but most locals do not look at animals in the same way I do as a valuable member of the family. One night at Souk wagif some local ladies were trying to sell a gorgeous 1 year old Himalayan so they could get a grey persian kitten they liked better, they seemed to have no relationship with the cat, like it was a thing. Its probably getting worse since their are less cats in the country.
