Isabelle needed help...
Isabelle was not microchipped and was definitely owned at some stage as she is friendly. She would benefit from a very kind fosterer. Nasty rescue who previously created various grief may not apply. They know who they are. They are the rescue who recently got reported as having rehomed a young cat full of fleas, not neutered and unwell, etc...
Isabelle needs a five star forever home once she is fit and well and vaccinated.
