My Cat Dior Was spayed about six weeks ago, however within the week has appeared to put on lots of weight and started producing milk within the last few days.

In june dior had a litter and was not happy when they were given loving homes.

However we did aquire another kitten a few weeks later and ended up keeping him (he was neutered).

within the last month dior has really taken to this little man and cleans and sleeps with him etc.

Is it possibble that she is mothering him and having a false pregnancy due to the neutering or is it something more serious?
