Ditto.
I would suggest that if you do not want to keep the little one then you ask a rescue to put it on their list of cats waiting to come in and get her spayed in the meantime. To anyone who thinks they have found a stray I would say please do not assume it has no owner (or assume it has), please report it immediately to rescues and any lost/found registers. It may simply be lost and could have been lost months previously. It is not unknown for cats to get into cars, removal vans, and so on, and be transported miles from their homes. Many so called lost cats are taken in or being fed by well meaning people, but are never actually reported. Depending on the condition of the cat and the safety of the location a rescue can decide what course of action to take to ensure the cat receives all the help it needs. E.G. if the cat is well please ring all lost and found registers, take the cat to a vet to see if has been micro chipped. If there is no record perhaps you could on a long thin piece of paper write do I belong to you and your telephone number then attach the paper to a cat collar by wrapping sellotape round and round then put the collar on the cat if after 3 days you have received no reply take the collar off as in Cats Protection opinion they are considered dangerous and many cats have lost their life to them. Please offer the cat shelter & feed it, i know some organizations say don't and they it will move on, however in our view that is callous, i am sure if you lost a pet it would be nice to think someone, somewhere was caring for it. Also the cat has a greater chance of finding its owner or going into rescue care as it is not roaming from street to street looking for its next meal and endangering its life.
I would also suggest that once a cat is established as a stray it is treated for fleas/worms and neutered/spayed.
