When I run this code, I receive a very vague syntax error: database: syntax error at or near "(". I am unable to find where this syntax error would be.
I have also been told that animal_adoption_history is not an associative entity when it was designed as one.
What have I done wrong when writing it?

INT(10) is not valid datatype:
There are other issues as well, you have to fix this.
You have a number of errors in your code. When running PostgreSQL only lists the first one, which in this case is the line
a_animal_cost INT(10),. Integers are a fixed size so it is wrong to attempt to specify a size for it.Also do not use char(1) for Yes (‘Y’) No (‘N’) fields. PostgreSQL has a native boolean data type for this purpose, so use it.
When deleting tables, you need to delete the lowest tables in the hierarchy first (foreign key etc).
Finally, you can chain multiple inserts as values together.
Putting all this together, I would recommend that you use something like this:
