Small updates...
Last night she refused to take a painkiller, because of the bad taste of the antibiotics. She looked quite fine so I said ok let's see ...
I think she was in pain during the night so this morning she was not as fine as yesterday.
I gave her the painkiller this morning but she looked very very tired during the daytime today (I think because she could not recharge her batteries because of the pain). At the end of the afternoon, my daughter and I gave her a long and good hug and massages and since then (maybe because she could rest thanks to the painkiller, too), she looks better - she gets talkative, eats well and drinks well again.
As I have work to do, I cannot be with her all the time, and certainly she would be tired (both physically and psychologically) if I do so.
I will take Moru to the vet tomorrow, as the vet will be on holiday for two weeks starting from this Saturday. I will update how it goes tomorrow.
Otherwise I have not changed the idea of adopting two friends for Moru. Maybe it would be difficult for them to live together in the same place, I will have to put a partition or something. However Moru is a very friendly pig and she would be delighted to have friends near her. They will be together for a couple of hours a day, if everything's OK, too. I do not know how long Moru can be with us, but I want to do everything I can do for her.
