You have Tara Kat in the bin. She already has a good start with three cats.

You can get any mix of pets that hate each other, just as long as you take out MATY's lesspetwarfare. Then they'll do nothing else but try to kill each other.

@>Charity > Yes a dog can died in a fire ( it is very rare ) but can happen if you got a household of stupid Sims who is always burning the house down. ( by mean of the kitchen stove )
I was over a Simmer friend house who live near me, she did not have any fire alarm , nor did the Sims have cooking Skills. She wanted to play her game in a dangerous kind of way, and she did not have a mod to stop them from running to a fire, or to stop them from starting a fire. Well the hold house soon burn down with the Sims and poor pet dog inside. There was only one Sims who survive a teenage boy, ( only because he was at school ) later on she told me when the dog came back as a ghost and family members they was all red in color. So I guess it can happen, anyway my friend know longer play her game in that style she said she started feeling guilty. lol
