Metamucil can also be used if ok'ed by your vet at 1g per pound of weight once to twice a day as needed to maintain stool consistency. It does not work overly well when used for an already blocked up cat, but if the situation hasn't become immediate yet, you may be able to try this first.
Pasteurization is the process of heating milk up and then quickly cooling it down to eliminate certain bacteria. For effective pasteurization, milk can be heated up to 145 degrees Fahrenheit for 30 minutes, but this method isn't very common. More common is heating milk up to at least 161.6 degrees Fahrenheit for 15 seconds, which is known as High-temperature Short-Time (HTST) pasteurization, or flash pasteurization.
Pasteurisation has long been used for the preservation of beer, following on from the work of Louis Pasteur. It is a process of applying heat to preserve food and drinks. It is effective in stabilising beer with regard to microbial contaminants and is in widespread use across the brewing industry.
