cat pooing in the house

[SarahBumBarer]

Aaaargh - this is really getting me down.

Luckily I'm pregnant so DH is having to deal with cleaning it all up but I was wondering if anyone had any suggestions.

Our girlcat has taken to pooing in the house. She is doing it most nights, last week she did it once through the day too when she had the opportunity to get upstairs while we were out. It started when DS was born (16 months ago) and seems to get worse when it is cold, shortly after a fight with next door's cat etc etc but it is far more constant than that. We had our garden re-turfed this year and she was fine while our back yard was just a mud layer but as soon as the grass was down it was back to indoors. We have some pretty large flower beds so why she can't just use those if mud is her thing, I don't know. We have tried litter trays (indoor and out), pheremone type plug ins, putting food outdoors overnight (to persuade her to go out). She even poo'd in her food bowl one night (which stunned both DH and me) and in our sink. Vet is adamant after several visits that it is nothing physical.

Nothing has really changed for her since DS was born since she never really liked spending time with us much (feeling is unfortunately becoming mutual especially for DH) unlike our velcro boy cat who has been royally supplanted and accepted it with good grace. We have had both cats for 10 years 9ben in this house for five).

Any suggestions? Are there any kind of heated beds etc that we could use in shed and so keep her outdoors (ie in the shed with outdoor access) overnight without her getting cold etc? I'd just like to be able to come downstairs of a morning without that feeling of dread and knowing that DS can potter about while I sort out breakfast etc. Obviously if she is stressed and unhappy then I would like to be able to alleviate that too.
