Making *that* decision - pet cat.

[CopperBolt]

Hi all
Ive got one moggy left, from 2 I inherited when Mum passed away 9 years ago. She must be over 20 years old, the cat that is...
She has liver problems, yellowish gums etc, tooth cavity on one or two of her remaining 4 canine teeth. Vet is fully aware of all these issues.
She is very lethargic now, lots of sleeping. she is on pain killers now, got given them last visit to the vet a week or so back. She was pretty lethargic before the pain killers so not a massive effect they have I dont think in that respect..
She is still eating really well. She will still come up for her "cuddle" and purr at certain times of day. She goes out into the garden occasionally(when its not raining or blowing a hooley) and has a slow mooch not very far. Has a go on her outdoor claw scratcher and comes back in for a sleep.
She can still jump up into the windowsill and onto "her" chair so not decrepit.

Its just me here and the house will be very empty once she's gone.
I dont want to take her on her last trip to the vet but not sure how I make the decision when I ought to. I'll either beat myself up for taking her too early or beat myself up for letting her suffer for too long.

Any advice?

Thanks

Thanks all. Her regular vet only works Thursday/Friday so was thinking this Thursday could be it.
If she starts falling over or stops eating or something then I guess that'll be the time.

I had to make the decision yesterday. My poor girl had been throwing up in the night recently, then on Monday twice in one day.
Also she seemed to be in discomfort all the time, couldnt get positioned to sleep and kept moving spot from chair to floor and back again.
Also hardly eating anything a few licks is all so the medication I crumble into her food wasnt getting into her.
Decided it had to be the time and booked her into the vet for yesterday.
Vet was really great. Finally I held my poor girl in my arms in her cuddle position as the procedure went ahead, then she was gone. A last kiss on her soft fur and that was it.
Needless to say missing her terribly and uncrontrolled emotion is frequent.. Thankful Im working from home but miss her everywhere I look. Hardest decision ever and two of the worst drives, to vet and back ever.
So long Phoebe.

Thanks to all for the comments and support when this thread started. Just updating as some sort of hope at catharsis.

Thanks all.
