Firstly, welcome to the forum.
Я приветствую вас!
Normally, new members are not allowed to put links into posts and this post was therefore subject to moderation. I have approved your post here, but have deleted the identical one on your blog. Please note that duplicate posts are contrary to forum rules.
I wish you well with your appeal. It is wonderful that you are willing to care for this poor kitten, given the costs involved. However, a few dishonest people (I'm not suggesting that this applies in your case) try to raise money by making false appeals. Therefore, to help members be sure of the genuineness of the appeal, please post the name, address, website and telephone number of the vet who has given this estimate. It would also help if you ask the vet to permit requests for information from potential donors.
As usual, I give the standard caution to any members who might be considering a donation: always check out the details independently first.
Every best wish to you and to the poor kitten!
