I'm not a vet but have had some cat experience. It seems to me that cats tend to eat a bit of grass to help them clear their hairballs. They also seek it when they have digestive issues of which a hairball could be one.
I use to have a cat who demanded grass on a regular basis...bought it in the house in a bowl and he ate it right up. Let the cat have as much grass as it wants and see where that leads. If something does change over 24 hours, then you should consult a vet.WB.
Animals eat grass to make them throw up or to clear up an upset stomach. It could be as simple as something they ate that did not agree with them, but it could be something more. It is really hard to tell.
I would bring him to the vet just in case it is something more. You do not want your pet to dehydrate.
Your cat isn't feeling well or may be actually sick. If I were you I would call the vet immediately. Grass is something like medicine for animals when they aren't feeling well they will nibble on grass on their own to feel better.
But don't take any chances call the vet asap.
If you have problem like this than you have to use an Artificial Grass and stop the chewing the grass. For further information please visit simplyturf.co.uk.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
