Walmart has some oat cat grass. It's in a container where you just add the seeds(in package) and water. It's susposed to be sweet and healthy. Also susposed to help with breath and digestive tract. Is it safe and good for Spica? (oh and I dont know if age matters but she is 4 1/2-5 months now). I cant find the brand or details on WM's website...or any other cat items...odd...well maybe you've seen it.
