I got tired of buying cat grass from Petco because even following directions of watering and refrigerating it never lasts long. So I grew some myself. I have 1 cat who could car less, but she goes outside and likely eats it there, my inside cat nibbles at it but does not seem to really eat it because it is still as tall as it was, should I be chopping it down shorter for her?, she does seem interested.Also should I be refrigerating it also from time to time?
