I have taken the link to the advert off now as it had a telephone number on it, but here is the main body of text
hello, i am hoping that there is a very loving familly that can help me.
i was born on the 26th of april . i have a brother and 2 sisters.i am a bit different to them as i seem to have a little problem with my back legs and am struggling to walk properly . i know i will need some help from a vet but my owner is not able to provide that as she is out of work.she is very sad as she does not want to have me put down but unless she can find someone to take me on love me and help me get my legs mended she will have no alternative. she is very loving to me like she is with my brother and sisters and she is teaching me to be loving too so dont worry i will love you and really be gratefull of a chance to live.
UPDATE:
I Plucked up courage and phoned the advertiser, she still has the kitten, I told her I would seek advice here and see if anyone could help, apprently the kitten is getting better at walking but there is still something wrong, the lady says she sort of bunnyhops everywhere. I really cant take the kitten on, I wish I could but we are virtually on the bread line at the moment, our lot are insured but insurance wouldn't cover this would it ?
