Just an update - Pixie had a check up on Tuesday and she's doing better than expected. She has an abscess on her gum so the vet actually mixed up a painkiller - metacam being contraindicated with CKD and an antibiotic.
Took a couple of days for things to kick in and is now eating really well. Her BP is good so the Amodip is doing its job. Ordered 60 tabs online which is 120 days supply.
I'm not a morning person but normally she demands feeding around 6am. Today I awoke at 6am worried because she hadn't woken me up. When she saw me it was straight to the food and this morning she's had one and a half sachets of renal food plus some senior gourmet.
