I realize it is midnight in Bahrain. Is there a pharmacy or health food store open 24 hours? You might try slippery elm bark. It comes in capsules and in a powder. Make sure that slippery elm bark is the only ingredient.
From here (I'm not implying that Meme has kidney disease - this is just the best source for information about slippery elm bark):

What Is Slippery Elm Bark? The natural remedy most commonly used for CKD cats is slippery elm bark powder (ulmus rubra or ulmus fulva). Slippery elm bark is a herbal remedy used for most kinds of digestive or intestinal problems - it can be used for nausea, vomiting, diarrhoea or constipation. As a side effect it can also improve coat dryness and dandruff.
Slippery elm bark is a demulcent, which means it soothes the stomach lining and intestinal walls and reduces irritation. This can be particularly useful in combating the nausea and excess stomach acid which many CKD cats experience. You will usually see an improvement within a day or two of starting slippery elm bark.

The Journal of Nutrition 134(8) pp2124S-2125S found that it also appears to help with hairballs.
Slippery Elm Bark Formulations
Unfortunately it is difficult to find capsules that don't contain magnesium stearate because it is a glidant used in the manufacturing process (it helps the powder flow when the capsules are being filled). Magnesium stearate is safe for cats but may affect the thickening of the syrup, though some people have been able to make it successfully from such capsules. There is one US supplier
below selling capsules containing slippery elm bark only.
gelcaps separately for this purpose.
Some people have found their cat will eat slippery elm bark if it is mixed in a little
baby food (make sure the baby food does not contain any onion).
Syrup Recipe
You can also make slippery elm bark into a syrup that is used for digestive problems or for mouth sores or ulcers. It has the same soothing and healing effects in the mouth - try dabbing in your cat's mouth ulcers if required. The syrup is weaker than the straight powder, so you can give a little more of it. Some people have told me they find it hard to place the syrup on their cat's mouth ulcers if they are in hard-to-reach areas of the mouth. In such cases, you may wish to use a syringe to aim the syrup at the ulcers.
If you are using slippery elm bark decanted from capsules, you need pure slippery elm bark with no fillers, otherwise the syrup will usually not thicken properly.
Stovetop Method
- Take a stainless steel or heat-proof glass pan (not an aluminium or non-stick one). Put one cup of cold water in the pan. Sprinkle 1 to 1.5 tsp of slippery elm bark powder on to the water. Let it sit until the powder is damp (this should not take too long), then bring to the boil stirring constantly. Reduce the heat and simmer, still stirring constantly, until it thickens, about 3 minutes or so. It will be the consistency of watery egg whites. Allow to cool and give ¼ - ½ (0.25 to 0.5) teaspoon up to 4 times a day. This will keep at room temperature for a day or in the fridge for up to five days.
Microwave Method
For the non-cooks among us, one of my support group members came up with this method but it may not work with powdered slippery elm bark. Take a glass container which holds two cups. Put one cup of water in the cup. Add 1 to 1.5 tsp of slippery elm bark powder. Heat in the microwave on high for about 1.5 minutes. Remove from the microwave and stir, then put it back in for about another 30 seconds. Keep an eye on it because you do not want it to boil over. Remove from the microwave and stir again. Allow to cool and give ¼ - ½ (0.25 to 0.5) teaspoon up to 4 times a day. This will keep at room temperature for a day or in the fridge for up to five days.
