Anyone with house cats knows what a challenge it is to enjoy both your love of cats and your love of plants. Personally, I've given up and my plants are either hanging or kept in a room the cats aren't allowed. If the kitties weren't using the plant pots as a litter box they were constantly either nibbling at the leaves or turning the plant itself into a cat bed.
So as a pet owner who tries to understand the whys of their behavior rather than just be yelling at them, the reality is, is that cats love to be close to nature just as humans do. They not only enjoy the taste of nibbling on grass, but simply enjoy the smells and feel of fresh greens.
We have to remember that in the wild the first part of the prey predators eat is the stomach and intestinal contents. Carnivorous animals receive lots of nutrients needed for their good health. Grasses not only contain necessary fiber for good digestion, but also the benefits of chlorophyll.
So I think cats eat grass for three reasons. They receive nutrition that may be lacking in their usual diet. Eating grass tends to make them vomit which is their way of dealing with a tummy ache and hairballs. And the fact remains that they just may love the taste.
Grass is mainly fiber and being a cat's stomach doesn't have the enzymes needed to digest it, the body induces regurgitation. Now to think like a cat there is good reason for a way to bring back up undigested stomach contents. If you ever watch a cat eat a bird or a rodent it really has no choice but to simply eat the whole thing, bones, fur, feathers and all. The body has no need for certain parts so to bring bones and hair back up, it is nature's way of preventing intestinal damage from the bones or intestinal blockages from hair balls.
Any cat owner knows how fastidious cats can be with their grooming. Unless you are diligent and periodically use a grooming tool such as a
furminator to help with shedding, your cat is going to be swallowing cat hair on a daily basis. If you have a cat in the house you just have to accept the fact that you're going to occasionally be dealing with cat vomit. Of course no one looks forward to cleaning up that wet pile of mystery contents nor the fight against the inevitable yellow stains that could spot your carpet or rugs. But no one wants the risk and cost of an intestinal blockage either. So don't make the mistake of not allowing your cat access to cat grass in trying to prevent any vomiting. With nothing to snack on, your cat will turn to your plants and since so many houseplants can be toxic, that is a risk too.
To
grow your own cat grass you will need the following:
1. Small pots
You should have more than one pot of grass growing so you can rotate. Cat grass isn't seeded once and be expected to grow and last very long. Between the cats' grazing, pulling it out of the ground, trying to lay in it, the grass eventually turns brown and falls over. So have more than one growing so you can rotate the pots and have a continuous supply to offer your kitties.
Don't bother using big trays. It'll look nice for a day but soon become a flattened mess from your cat laying and crushing the grass.
2. Organic potting soil
Get good quality potting soil such as Happy Frog. You don't need the risk of your cat ingesting fertilizers, pesticides or herbicides that may be in ordinary soil.
3. Cat grass seed
Wheat, oat, rye or barley seeds are the usual but wheat and oats are the most common. You can buy the seed already labeled as cat grass seed but to save money go to a natural food store that offers bulk raw seed. As long as you keep the seed dry and out of the sun it should stay viable for a few years.
4. Plastic wrap
Grass needs moisture and warmth to germinate. By lightly covering your pot with plastic wrap it increase and speed up the germination rate of the seed. Once the seeds have sprouted you do have to remove the plastic or your pot will mold.
5. Spray bottle with water
The seed has to be kept lightly moistened until germination so it is handy to daily mist the soil surface until the seeds sprout. To just water the whole thing increases the chance the seed will be too wet and not sprout at all. Once the plastic is removed you can water as you normally would.
Steps:
Fill your pots with the soil up to 1-2 inches from the top.
Sprinkle a thin, even layer of seed over the surface.
Cover with about 1/4 inch of soil.
Wet the surface but not to drench.
Cover the pot with plastic wrap.
Put the pots in a dark, warm area. The top of a fridge is a good spot.
Check daily for signs of sprouting, mist if the soil appears dry.
After a few days you'll see signs of seed germination.
Keep the plastic on until the grass is an inch or two high.
Remove the plastic and place the pots in a sunny location.
Once the grass reaches 4-6 inches in height and established, you can offer it to your cats.
If you give them access too soon the roots won't be anchored yet and pull out too easily.
Put the pot on a tray or somewhere you won't mind a little mess. There is a good chance you'll find some grass and dirt outside of the pot.
Cleaning up vomit stains:
Remove the solids and blot blot blot the excess moisture. Don't rub, blot!
Sprinkle baking soda on the area to neutralize the acids and absorb any remaining liquid.
Let the baking soda dry, then vacuum it up.
Follow with a splash of club soda if any stains remain and blot it up.
Remember, don't scrub it while it is wet or the stain may be driven deeper into the carpet fibers.
If you notice your cat actually binging on grass there may be something wrong so it may be best to pay a visit to your veterinarian.
If you do let your cats outside try to keep their wandering limited in order to not only keep them off the road but to be sure they aren't snacking on grass areas that had been sprayed with herbicide or pesticide.
The ultimate in cat greens pleasure is catnip. Catnip is in the mint family so doesn't make a very good houseplant but can easily be grown outside during the summer. If just planted it will return wherever it pleases so unless that doesn't matter to you, be sure to plant it in pots. Catnip is easy to cut and dry so that you'll have plenty to offer your indoor cats. Here is a good
post on the subject of catnip.
