Hi there.
to Purrs. I hope you find your purrfect partner. Just a word of advice though, as this is a public forum I'd be inclined to remove my mobile number if I were you, and keep contacts to personal messages. Wouldn't want you to get any krank calls.
As we are predominantly a rescue site, I'm going to add to Tiggy's Mum's excellent submission with a general link to our sister site Catchat. It would be worth your while phoning around a few rescues in your locality, not just the specific Siamese rescues, to see if there's a "made for you" match just waiting for your call.
You never know it may not even be a Siamese who calls to you.
And of course there's always Paws Inn in Weaverham, Cheshire, not a million miles from you, which is one of this Forum's closely associated rescues.
Good luck and do come back to us when you've found her!
