HI I am Dr. Skelding. I have a few questions.
Did your vet do any blood work to distinquish wheter she was having kidney issues, or diabetes, as Both will cause an increase in drinking.
Is Sweet Pea straining to defecate?
She did blood work a year ago when I told her she was drinking lots of water.
The vet put her on Hills Prescription DIet k/d feline Renal Health food.
She doesn't even seem to be trying to defecate.
About a week and a half ago I do remember letting out a slight cry when she did deficate, but other than that she seems her normal self. She's still drinking a lot.
Bloodwork a year ago, is not relavent. Older cats get a syndrome where they can't defecate. Double that up with kidney disease or diabetes and you have a very constipated cat.
If she doesn't have kidney disease, then waiting until Monday would be ok. But, if she has kidney disease she could be much worse by Monday.
If you are satisfied with answer, please push the accept button and I will move on to the next question.
