Well hubs is now firmly attached to our cat and he & daughter have ganged up on me to 'at least investigate' taking our cat back to Australia from Thailand.

Oz quarantine is very restrictive. Cats must be imported from an 'approved' country. The nearest approved country to Thailand is Singapore. The cat must spend 6 months in Sing (30 days of which is in their own quarantine) before being eligible for import to Australia. On arrival in Australia she would then spend a further 30 days in arrivals quarantine.

Sounds like 7 months in kitty hel_l to me, but there you go....

In Singapore she would need to board at a cattery for 5 months (after she finishes her 1 months Sing quarantine). Anyone been through this/got any recommendations of places?

Customers of mine took their cats back to Singapore end of last year. So they should be able to tell you where the cattery is.

You can try to pm one of them: tv-member alexisthetiny

If you can't reach them by pm, please, pm me. Then I can try to email them and set up a contact between you and them.
