Shrews Toxic Hillbilly Cousins

Shiba Rewards mascot, Shrew, has a large family from the backwoods in the Southern US. They call themselves hillbillies as a term of endearment. Family is everything to them and they would give them the shirt off their back.
Unfortunately in their backwoods living, they experienced a toxic dump and its contaminated their fur and teeth!
What’s worse, their poor pets got the worst of it! Each of Shrew’s cousins has a pet and a select few have a VERY limited pet…..can you find it?!
