I had submitted this question earlier today but had problems with the site. I have been feeding 2 feral sibling cats. Both are about a year old-one grey & the other is a tortishell. The grey has now had 2 litters this year-last one just delivered on 7/29 (1st one about 5/1). She was attacked by a coyote a month after having the 1st litter & disappeared a few days the last week of May. The torti was pregnant in May but it appeared she had her litter too early & lost her kittens possibly to miscarraige? While grey was missing for those few days - torti took over caring for her sister's litter which is 3 months old now. When the grey one recently went into labor - she persuaded the 2 kittens from her 1st litter to go with her even though she would have nothing to do with them after the coyote attack. What I need to know is why she did this? I had more details in my 1st question but am now skeptical about this site. Can anyone offer any answers? It is appreciated.
