I feel for you. I found a ferel in my garden about 3 weeks ago. Had her checked by vet recently and she is around 12 weeks. She is coming on brilliantly and I'm very attached to her.

As for the costs I could have done without it really. I already have 6 mnth female that I'd just paid for a Spaying. I thought for a while thats all I need to pay out. But this little thing just came along and I do feel its MY responsibilty for taking the very best of care of her. Initially its not cheap. Vaccs are £27 for 1st course and then another £27 3 weeks later. Nuetering needs to be done at a round 5 1/2 months. There is worming and fleaing which I guess varies from vet to vet. But once you get these over with then the annual costs are really very reasonable compared with the love and entertainment you will get back from your kitties.

HOWEVER - I can go without a few luxuries. If you take these on then their health is paramount. Good luck and let us know how it goes.
