My elderly cat (18 years) has been very under the weather for the last few days. She has hyperthyroidism and has been taking fairly strong medication for the last few years. The last time her medication was increased the vet warned that it could potentially be damaging to her kidneys - but the meds made such an improvement to her quality of life so we went ahead.
Her kidneys now seem to be failing. She is drinking and peeing loads, has lost her appetite and is very lethargic.
I took her to the vet this morning and he started talking about blood tests and further investigations. She is not good with blood tests and needs sedation before they can be taken (even by the most senior vet at the practise). To me it seems obvious that her kidneys are failing.
He gave her 4 different injections this morning - anti-biotics, a steroid, vit-B and something to support her kidney function. He wants to see her back in 2 weeks (as long as she makes an improvement by the weekend).
I'm not sure it's fair to put an elderly cat through this. Is it time to say goodbye. At present she has no quality of life - she is miserable.
Any advice?
