It's common for cats to throw up periodically when they've got too much fir in their stomach. Unfortunately, it brings on spots and smell which aren't easy to get rid of. Dogs have their own issues, and if you have small kids you might have a similar problem!
I've tried bleach but it's not very effective. Having read the reviews of the product left by others who have experienced this problem I decided that the enzymes should do the job what other chemicals couldn't and wasn't mistaken.
According to the description and reviews, the product can deal with all sorts of spillages made by man or animals. It did just that in our case, quite effectively.
I like the fact that there is a generous amount of this stuff to cover my whole house and leave some for future problems if they happen. I just need to buy the black light in order to make sure that I've addressed all the problem areas! ;-)
