Previously outdoor cat refusing to go out

[choosername1234]

Hi,
I have a 4yr old neutered female moggy who has been an outdoor cat from as soon as she was able to go out. She has always been confident outside & would happily come in for food & was usually inside overnight but always toileted outside (we didn't need a litter tray).

We went away for the first 2 weeks of August and put her into a cattery / cat hotel. We did this because last year we went away for 1 week and the cat poo'd & wee'd through the house despite frequent visits from a neighbour to feed & stroke her (litter tray provided whilst away was always cleaned).
Since she came back from the cattery, she has not left the house & has been using the litter tray we have had to provide for her. She is still eating well but does nothing other than eat, sleep & poo (and wee).
I'm worried because this is such a change in her behaviour. We have tried a felliway plug in with no obvious benefit noted. Any advice welcome, thank you

I have asked for this to be moved to The Litter Tray

So long as the animal seems content I wouldn't worry. At least she is using a litter tray now.

True, but the sudden change has me worried.
Anyone else please....?
