I got myself into a mess and it feels like I can't get out

I've always wanted a pet cat, but my mum was allergic when I was younger. I've had a few dogs.<br><br>When I moved into my first flat, I decided I'd look into getting a cat. The people at the cat rescue centre said I should get a dog, because I'd never owned a cat. They recommended I foster a cat first to get a feel for it and they would cover all of the expenses. I initially didn't like the idea but eventually went through with it. The first animal I was given to foster was Tiny and he was a dog. I've recently found out that the cat rescue centre is no more and that the woman in charge of it was completely corrupt. So now I feel resentful because I don't think I was given an option to foster a cat. I've missed my chance to own a cat now.<br><br>Tiny is a 4 year old shih tzu - he was 1 when I got him and I was told to foster him for 2 weeks and then he would be collected to be rehomed. He was picked up after 2 days. I heard nothing from them or him for a month and they called me asking if I'd foster Tiny again but for longer. I said yes and they told me it would be about a month. He was dropped off. I got a phone call the next morning from a man saying he was the boyfriend of one of the women from the cat rescue centre and that the centre's been shut down due to issues with management. They have been rehoming pets to other people while also selling them to other people to make a profit, and telling the original owners that the pets had passed away. They didn't know what's going to happen to Tiny, he may or may not be collected but they won't know for a long time. I called the police on the boyfriend, not because I wanted him in trouble but because I knew he was committing a crime by talking to me about it and it would look bad on him. I wanted the information.<br><br>I told family/friends about the situation and they all said I should just keep Tiny and they explained to me that he'd have to be rehomed to a completely different rescue centre, which would mean sending him to a shelter. All of my family and friends have pets of their own so it was no use asking them to take him in. I decided I would keep him but I've never had a dog before, you see. In fact, I've never had any pet for more than a month before and now I'm stuck with him. He's awful. They said his name is Tiny but his microchip says Sammy. I've never had a dog and he's so hyperactive. I don't have the space or the money for him and it's just really hard. My flat is a mess and I've already got a claim outstanding because of him destroying my carpet. He never calms down, he's always jumping and barking and I end up losing my temper with him and hitting him. I don't know what to do.<br><br>I feel so angry that I've ended up like this. I should be able to sue the cat rescue centre but it's gone, so what then? Am I just fucked?
