freaking out

SO I have been house sitting for Emma for a week and her mom always tell me when i come help with the dog and cat that the scat that has no nails and has been an in door cat for ever that goes out every now and again has been bring in dead birds and moles. Yea so i have to close the door so he has to meww to come back in. Not a problem but yesterday the dog that i have always loved brought in a dead baby bunny yea i dont know if he killed it or found it dead and brought it in but just dropped it like nothing ever happened. Well today he brought another one but i didnt see him come through his doggy door so unless it was something like he brought it in and put it somewhere in the house last night or he was really out there. Omgosh i dont know what to do. its soo gross. and ofcourse he brought this one in when i was the only one home so i had to go throw it away and not had chris or ryan to throw it away for me.
