Hi everyone, and thanks in advance for reading.
Doro and Tiana (male and female) are the two kittens living at home, they both are three and a half months old.
He was picked up from the street when he was around 7 weeks, he is growing healthy and full of energy.
We thought that feline company would be good for him, so we adopted Tiana from a shelter, but her arrival was delayed because she's been sick. She is better now, but has light apetite and still needs to gain some weight.
When she got home last week we made a progressive introduction. When they first saw each other, there was some hissing and he chased her. We kept them in separated rooms, but the following encounters, which also went progressively, were no better.
At the beginning they smell and observe each other, but he quickly starts chasing the female, repeteadly holding her from the back, biting her neck, with signs of dominance (or even mating?). It all starts like a game but turns into something unpleasant for her, with cornering, biting, screaming... The extra problem is their sizes, despite being the same age, his weight is almost twice hers.
When they are at the same room he is 100% focused at her and hardly gets distracted by playing or food. We do not know if he has an agressive intention or he's just playful, but she ends up seeming scared.
Here is a short video of one of their encounters. They are still in separated rooms and we are worried about the situation, because we don't know wether to restart the introduction slowing it down, or to let them figure out things their way.

Would really appreciate any advice.
Thanks again and regards from Barcelona
