Sas, I have been thinking about you all day.
I had a feeling that Ti's breeder might not show up today.
I seem to recall it was the same way when you got Ti that she originally said Sunday you could get him but then put it off until Tuesday so you had to take time off from work.

What worries me is that Ti will still be at your house on Monday night when Miley gets back from the vets.
Have you asked any of your neighbors or friends if they could just put up Ti for the one night?
I can check with a couple of my friends to see if they could help temporarily at least.
Please let me know if you do end up needing to rehome Ti yourself, then I will dig up more contacts who should be able to help you. Hang in there!
