Our 13yo cat has a large tumour in his abdomen which is causing v unpleasant toileting and the vet has said it's inoperable as too large and he is too old so they want to put him down in the next week or so
It's very sad as he's quite a character but he's a good old age and it's just his time.
As he wasn't apparently in any pain or discomfort and is still merrily eating they've let us bring him home with some steroids but have warned us that the decline will be rapid and already he's slowing down (not that he was fast before!) and looking a bit dopey and unsteady.
I don't want to prolong it any more (we've already known for about a week and DD is distraught enough as it is without dragging it out) but DP keeps wittering on about he doesn't look any different to him and maybe he'll go on for another month or so 
He's in complete denial and it's pissing me off now as I don't want the poor cat to suffer but as it's "his" cat (from just before we were together) I can't seem to force the issue without seeming like a heartless cow, but I think he should be the one to take him as he's mentioned wanting to bury him afterwards. It's looking like I'll have to deal with it and bring home a dead cat but I'm heavily pregnant with hyperemesis and feeling like shite so would rather not (am also thoroughly sick of being the one who has to 'sort' everything) but apart from it being totally unfair on the poor cat I don't want to be on maternity leave having to deal with horrendous cat diarhorrea daily just because he's too cowardly to accept the inevitable.
How to I get him to man up and sort the poor bloody cat out?
