Purina Petivity At-Home Kidney Health Test for Cats, 1 count

I expected my cat would test positive for mild levels with this test, and she did. She has early chronic kidney disease. I used this at home to ensure her kidneys were not imminently "tanking", to make sure she was not in an organ failure crisis when she had an adverse reaction to a medicated arthritis treat. This certainly doesn't replace a workup at a vet but it's a decent tool for at home management of a chronic condition and determining whether sudden symptoms might be kidney related. I had tl use both strips because my cat doesn't like to be handled. The first strip u could only hold to her gums in 2 second increments and that strip displayed zero urea, which is not correct (chronic kidney patients will have some level at all times, not zero). I was able to hold her down for about 6 seconds for the second strip and that one came back as mild urea presence which is more expected. I'd appreciate if this kit came with 3-5 test strips, anticipating that cats do not like to be held down with something pressed to their gums. More strips also help validate the results in cases where a user isn't sure the gum contact was appropriate. Instruction on what to do if a test strip wasn't held for 10 seconds is also needed.
