So sorry to read of your loss, our pets become part of the familydont they
I have lost a few cats over the last fewyears, 3 were very old, one who was 13 for some reason wandered off, they usually never went far,she was run over, i lost my lovely Siamese boy to kidney failure 2 years ago, and my 14 year old bengal to a tumour last year and with 2 weeks my bluepoint ragdoll girl to hea failure,
I have left 2 Ragdolls who were housecats,but now go into the garden, and nowhere else, Ragdolls tend not to go far, and because they were originally house cats woud be too nervous to wander, although my back garden is very enclosed,
I also got a little dog 2 years ago, rehomed from a young couple with a crawling baby, Lola was a rescue dog originally and shes lovely
As for you getting another cat,i would see if Chloe settles on her own first after losing Sasha, my bengal was used to sleeping with
the last ones i lost,but seemed ok after a while
I think i would consider carefully about another adult, they often are fine with another cat, but the resident cat isnt always fine with them,
Whatever you decide good luck
PS,i had a Sasha and a Chloe too
