After all

Just like we tend to believe that the grass always seems greener on the other side of the fence, the neighbours’ homes always seem just a little bit more put together than your own. It is not uncommong for some people to wait patiently for a neighbour’s home to go on the market so that they can snatch it up right away, only to find that they are disappointed with what they didn’t know in the first place.Making a home amongst neighbours implies that you are making your own home. Home owner jealousy isn’t likely to get you anywhere you really want to go. Why not simply focus on your own home rather than drooling over the neighbor’s home? When you focus on what you have instead of what you don’t have you tend to be a much happier individual. Each one of your neighbours can find something wrong with what they have as well. Skipping from house to house can be unsettling, not to mention it is financially costly. Staying in your home, appreciating the work your neighbours do, and creating your home in your own reflection is much less time consuming and costly that chasing after what you don’t have. After all, when you own your home you also have the ability to determine what you want for your own home. This is something your neighbours can never do for you. Truly, home is where the heart is and home is where you can create your own palace.

Neighbors and their pets

More paradoxes are in the area, which deals with the inconveniences caused by neighbors’ pets. After all, you can make even a crocodile and it does not ask neighbor’s permission. Moreover, a violation of the rules of range of most animals is not punished, if they do not lead to other violations. That is, until a neighbor simply removes malicious bullterrier to walk without muzzle, fault, from a legal point of view it is very difficult. But as soon as dog someone bite (preferably with witnesses) - in the bag, can be filed in court. In exceptional cases, if, say, a dog is not just a bit, but also caused serious injury, you can even put the issue of forced seizure dog and placed in a special hospital. 
As for the odor emanating from balcony a zoo, and there is no one hundred grams will deal not. This seems to be a violation of animal health standards. However, the special agencies normally restricted to observing the violations and do nothing to address them. If you are want, you can try to prove in court that living next to a dozen screaming and leaving droppings behind a wall of cats or the pig floor below is impossible. Or that you specified the law violated the right to a healthy environment. However, for failure to comply with a court decision last after some time will be fined. Others are actually the existing mechanisms do not exist here. 
The case is hampered by the fact that the animals belong to private property. A trespass on it - it certainly is not grateful. However, if your neighbor lives in non-housing, you can try to influence it through the municipal authorities. For example, you can press on that living space with a pig on the balcony is not used for its intended purpose, and even for commercial purposes.
