well, I contacted the local vets and they said 'we charge the same for jills and hobs with the spaying procedure, both are 63.75' this is way more then I expected. I think ill find out the jill jab cost and ask around at other vets.
Also, with the whole price thing do you think a rescue ferret @ 25 pound with neutering etc would be the best option? most people ive spoken to say the reason theyre probably abandoned is due to them biting etc but to be honest I know most will be just unfortunate and will of escaped or will of had bad owners.
