Hi Lisa, I am sorry to hear about Portia and you having to rehome her, that cant of been an easy decision for you to make, I notice on CatChat you have posted that she is now not eating, you really really need to get her to the vets as soon as possible, it is quite urgent if she isnt eating, is she drinking OK ? in this heat she will probably need to drink a lot more than she normally does. Also please please dont take another kitten yet until things are sorted (i noticed your post on here saying you were looking for another cat/kitten), they all cost money and need vet treatment and sometimes it can be very unexpected, one of my cats had an infection and literally got sicker and sicker by the hour, we ended up rushing her to the vets at 10PM which was a £150 call out charge before they had even given her any treatment, she was an otherwise healthy cat that had picked up an infection that literally would have been fatal had we of waited much longer to get her treatment. I know it is hard when you see posts for kittens looking for homes, they all have really sad stories and you want to take them all and look after them, but we just cant help all of them out there. I wish you loads of luck homing Portia, but I would stick with Rosie for a while as a single cat, let her recover from her operation and see how things go in the future re another cat/kitten.
