Limestone is by definition a rock that contains at least 50% calcium carbonate in the form of calcite by weight. All limestones contain at least a few percent other materials. These can be small particles of quartz, feldspar, clay minerals, pyrite, siderite and other minerals.
Answers (4) You have not mentioned the name of the medicine in your post. Ideally 4 times a day means every 6 hours. It depends on what the medicine is as to how rigid you should be in regards to dosing. If the medicine is an antibiotic then every 6 hour dosing is important as is pain relief medication if in severe pain. If the dosing isn't so critical then 4 times a day could be evenly spaced out during the waking hours.
Administration. Buspirone is available in tablet form. Your vet might prescribe a 5 milligram pill twice a day for the first week. If you don't see a response, your vet might up the dosage to 7.5 milligrams twice daily for a week. If your cat still isn't responding, it's likely buspirone isn't the drug for him. However, if the larger dose does generate less inappropriate elimination, your vet might wean your cat back to the 5 milligram dose twice a day for a week.
