Cat Grass - When Is It Too Much? (Begging for the green stuff)

Hello all.

Our little baby Cibo is almost a year old now and she is a very sweet and oddball little kitty (but who isn't? ).  I can't seem to find any articles in regards to this topic and I haven't had any luck searching the forums, so I apologize if this is a duplicate.

Little Cibo seems to have developed an obsession with cat grass... to the point that whenever my significant other goes outside to water the plants (since we are growing some) she mews and begs excitedly for the green stuff.  We even have had to start growing it inside because she loves it so much.  However, we have been making sure she that she doesn't "gorge" on it.

My question, which I can't seem to find, is thus:  When is it too much kitty grass for her to eat?  Also, I have heard that you should contact a vet if they want to eat it every day, but why is this so?  I know that grass is relatively indigestible to cats and they eat it to purge and also to supply themselves with folic acid, but is it weird for little Cibo to beg (ever so cutely) for grass all the time?  Could it be that she's missing nutrition in her diet?

Thanks!

I would guess that the advice saying to contact the vet if they want too much may be because the cat may have a vitamin deficiency. Cravings sometimes indicate that the sought after food has a vitamin or mineral we are lacking. For instance, cravings for crunchy snacks sometimes means we need salt. Pickle cravings could indicate potassium.

It's hard to gauge a general "too much". Mo, our older cat, is obsessed with it. I had to move the plant out onto the balcony because he would snack on it all day and then end up constipated or throw up. After two days in a row of green grassy regurgitation, I had to remove it. Now that you mention deficiencies, Mo's blood work a month or so later showed he had low protein and was anemic, but anemia can also cause cats to lick lots of random stuff (and he licks everything) so I'm not sure how the grass factored into that.

If you haven't had a recent check (like an annual one) for Cibo, it can never hurt if there's potential for concern. At the very least, it'll put your mind at ease in that respect.
