I had to get a urine sample on Katie, and the first couple of times I used a plastic pint sized container or a baby food jar. I though I just missed, and each time Katie outsmarted me. After that, I just stuck a paper place under her and transferred it to a container afterwards. My vet said that it didn't need to be totally sterile.I would definitely try earlier than you need it; it can be refrigerated if you get it before you can take the sample to the vet. |
