<human>: I am a 19 year old college freshman. I have 6 siblings, so there are a total of 7. 5 of us are adopted, including myself. I was adopted at a young age, and so were two of my sisters and my little brother. Our age range is 32-12. We are all pretty much adults, except for my little brother, who is in 6th grade.

The same year I was born, my mom was involved in a car accident that changed her life. She has had multiple back surgeries, and as a result, has nerve damage. She was diagnosed with breast cancer last year, and she is in remission as of now. 

As a result of life just getting to her I guess, she has acquired quite a few animals. 7 dogs, 3 cats, and 4 rabbits. The dogs are one of the biggest problems in our home. She refuses to get rid of them, even when they present clear health problems. They are not trained, they bark at everything. Any attempt to tell her that we are sick and tired of them she just gets frustrated and blows us off. It's been like this for years.

My little brother is what im concerned about the most. Hes at a point in his life that could make or break him. I honestly don't think my parents can raise another kid. My mom is 60, and my dad is 59. They should be retiring. My little brother is no saint. He was diagnosed with a learning disability (I cant remember if its ADD or ADHD) when he was young. 

I think his environment is going to affect him in the  future. Ive thought about calling CPS, not because my parents are bad people, it's just this isn't a place for a kid to grow up in. But at the same time, I feel as if taking him from my parents would be terrible for him.

Can you give me the gist of the text in a nutshell?
<bot>: i feel as if my parents are to old and worn from raising a big family, and its affecting my little brother and his life.
