I don't actually own one yet..I'm doing research and waiting for the g/f to give me the okay for the expense. (I think I've settled on Janty) But, tbh, I'm not that accustomed to the units in small quantities, so I had no idea what would be a reasonable proportion. You also have the fun volume/weight switch up. From fostering (and having to inject kittens with saline in the process) I'm pretty accustomed to the size of a ml, however.
I'll be sure to keep the stuff away from my dogs when it gets in. I'll probably put a positive lock on one of my desk cabinets for it, since the cat is a bit of a ....... too. Thanks for the warning.
