cat grass question

[Abby&Buddy'sMom]

i have a question for you all. awhile back my husband bought from our grocery store a container of "cat grass" for abby.she loved it,and i let her nibble it once a day. eventually the planter of cat grass died..so we have not had any for a long time now. I want to ask .... can grow some cat grass by using regular grass seed that is meant for the lawn , or is a special breed of grass that is recomended for cats only. i dont want her to get sick on anything since she is my much spoiled baby. but i thought she would like a special treat again. thank you
