I'd also place two bowls of water out, one in the same room and one for her. Measure the amounts in each, one she has access to and the other she can't access. At the end of the day, measure the amounts left in each bowl. Subtract the difference of the bowl she can't access from the bowl she can access, that will be the amount she drank taking into account any that evaporated.
If she's peeing more often, she may have a Urinary Tract Infection. Are you able to tell the amount she's peeing or are you judging by the time she spends trying to pee? |
