to have a pet at home is a very good thing. and it is not important what pet you have. you may have a dog, a cat, a hamster, a parrot or a fish. the most popular pets are cats and dogs.

a cat is good for a small flat, and if you live in a big flat or a house you can keep a dog. it’s much simpler to have a cat because you don’t have to walk a cat every day.

dogs are best friends of people. these animals are very clever and understand you very well. but you must remember that keeping a dog in a flat is not that easy. you need to walk it two or three times a day. so, you have to get up earlier in the morning and it also takes time to feed the dog. dogs are hairy animals and they have a specific smell. nevertheless, dogs are wonderful animals. i love dogs.

people usually keep hamsters, rats, mice and rabbits. these animals are rather easy to look after. these animals are funny, but all they do is eating.
