Hi there!
Just want to thank you all for the support,
She made it! I was worried that due to her age (she is only 7 month) she would not be able to take care of the kittens properly, but she is such a good mother!!
She is fine, tired of course, but the kittens are ok too, no sign of distress and she ate that "thing" in the first pic, i think she has finished now.
I guess it was a kitten who unfortunately didn't developed in the womb.
About the vet, i got his number, i just didn't contacted him yet.
(Sorry...
Please help me,
I'm afraid there is one more to come and it has been a quite long (more than 2 hours ago) since she delivered the 4th kitten.
Is that normal?
I will send 2 pics
