The old girl was doing a lot of licking at the nether region so off to the vet we went. After getting an elevated blood calcium reading I was advised to be on the lookout for anything unusual. Turns out she has quite a urinary tract infection which we are now treating with antibiotics. She had an issue with an anal gland that got expressed, too. We're hoping that was the cause of the calcium being off. This girl certainly hides her discomfort well as there were no signs of a UTI other than the licking.
While paying for her visit I got a call confirming my knee surgery on February 22. Glad I got the earlier date so there is less time for worry.
