We have a lovely elderly lady - around 14. We adopted her from a rescue age 7. Condition of her adoption was that she should be an indoor cat.
She's had a bad time of it health wise. Heart murmur. Hyperthyroidism, which was initially treated with tablets. Then she had a rare auto-immune reaction and nearly died. Spent a week in cat intensive care. Eventually we took her quite far from home for radioactive iodine treatment a year ago. That was amazing for her, but her bloods at the time suggested some kidney issues.
She's now on mostly dry kidney food, half a sachet a day of normal senior food as the wet kidney food made her breath smell so bad I couldn't take it any more. She's slowing up, but generally happy and purring. Likes knees and radiators more than she used to, rarely climbs the stairs.
Vet check up today for vaccines - she's lost quite a bit of weight, has bad teeth (longstanding, inherited from previous owner only feeding wet food) and they think possibly in kidney failure. A dental general anaesthetic could kill her. She also hates the vet and has to be drugged to go.
I'm thinking no more investigations, just keep an eye on her and if she looks like she's suffering, the kindest thing would be to let her go then. Would you do the same? She's been messed about with so much already... we have insurance, so it's not a cost issue. Just want what is best for her.
