We have exchanged many e-mails with his owner and finally talked on the phone yesterday, and also talked with Armani's vet this afternoon. Also I have consulted my vet. HE IS MOVING IN WITH US His owner will put him on a flight next saturday.
As I understand, his problem is very minor, and they are not even sure if there is a hole or not. It is not clearly visible. It is something we should monitor, and no need to medication.
Well, as Claudia said, I am following my heart. After my previous himmy, Roger had died (I had adopted him when he was 10, and died at 12), I said to my husband that I wanted to have another himmy with a broken heart, and care for him/her. I did not exactly found one with broken heart, but I found one with a tiny mini hole in the hear And I was not even looking for one!
Thank you all for your suggestions, and I will keep you posted.
Bye for now...
