Re: How can I make my pets live longer? Any mods?
@Sunny_Rio I found one mention of a Sims Asylum mod to stop minor pets (i.e. not cats, dogs, or horses) from aging. You'd need to make an account to see anything on the site. Here's the discussion on the official forums:

I haven't tried the mod myself, but the Asylum mods are generally well-made and do what they claim.
