My mom is that way. I can't even count the number of animals that she has had since I have been married for 12 years, of course she doesn't have any of them, and most of them I am not sure what really happened to them. After she got the last puppy and kept it for a month or two, I decided the if she gets another animal, I will call animal control on her. We took one dog and one cat away from her but I can't keep taking in animals everytime she changes her mind. I do have to say, there are alot of people who don't think twice about getting rid of an animal when it gets to hard. I have to neighbors, one just got rid of her cat and another is looking for a new home for her dog, just becasue she doesn't want to pay $25 more a month for rent!
