Q: i need help hopefully someone can answer before wensday: A cement is a binder, a substance that sets and hardens independently, and can bind other materials together. it was made from crushed rock with burnt lime as binder. Cement (as in Portland type cements) is made by heating limestone to 1450 degrees C, then grinding the result into fine powder and adding a small amount of clay. When mixed with sand, stones, or other aggregates, the result is concrete. Cement hardens by hydration, absorption of water, and not by drying.

Call your vet and any vet in the area and explained what happened. They might have to shaved her totally. Just make sure she get some help because her skin is not breathing and it will only get worse. Please update and let us know how it goes. Sending lots of vibes for this kitten.

Q: and also does the cement have an affect on the water quality, such as ph, hardness...etc?and also if i do build it out of cement, do i still have to put down a pond liner?and also does anyone have any advice, or info on building a pond out of cement?THANK YOU: rubber roof liners work muck better and are cheaper than cement. Cement will give you lots of problems and the rubber last forever. I have one I built over seventeen years ago. The dogs, deer etc use it and it's still as solid as if it were built yesterday. You will need lots of help to place it as it is very heavy. I hope to enjoy mine for many more years. gail
