multiple checkboxes with the same name

[vijk2001]

I have a form with three checkboxes and multiple items shd be selected BUT

<form>
What type of pets do you have?
cat <input type="checkbox" name="pet" value="cat">
dog <input type="checkbox" name="pet" value="dog">
rabbit <input type="checkbox" name="pet" value="rabbit" checked>
</form>
IF I SELECT MULTIPLE ITEMS AND CLICK ON SUBMIT BUTTON.
THE QUERY submit_query WILL HAVE TAKEN ONLY ONE VALUE.

E.G:
CLICKED ON DOG AND RABBIT.
QUERY TAKES INPUT AS "DOG" NOT AS "DOG RABBIT" .why????

In ACTION=SrvGetParams

I AM USING SERVLETS FOR SERVER SIDE PROCESSING AND MY STATEMENTS are

String AnimalType = request.getParameter("AnimalType")

Then construct my SQL query as:

query ="scratch..submit_query "
+" ' " +AnimalType+ " ' "........
......... other form params...!...
