Adding scent to loop

Last year I lost a cat when draining out my water cooling loop (she was a young shelter kitty, sad her already bad life was cut so short). I don't want this to happen again. One of the major problems is it's not easy to remove the liquid without spilling a single drop. Plus I don't have a container to dump to the stuff into easily without having it open for animals to drink it. Without taking any expensive or hard precautions, I want to prevent it. I was thinking adding a little "Liquid a**" (that's the actual name of the product) to the water to it, but I'm worried it's not long-term safe, or safe at all for that matter, in a loop. Any ideas of something I can add to the loop to add a bad scent that animals hate (ok, butt scent may not be dog-proof)?

**EDIT**

Just to be clear: The cat died from the deadwater in the water (roughly why animals drink anti-freeze, the scent and taste). I basically need a bad scent to cover up the smell of the biocide and drive the animal away. I need to get some additive safe for water cooling loops, for PCs to add. Any non-deadly biocide suggestion would also be helpful.
 
Solution
Use a Kill-Coil instead of a Biocide (likely Copper Sulfate/Sulfide), Silver is pretty low on the toxicity scale.

In terms of stopping your pets drinking it, no idea. Most I can suggest is a taller bucket.


Thanks! I had a kill coil but I put it in and I never found it again. Do those things dissolve into the water, or do you think it's just stuck somewhere in my res?
