DEAR READERS: I feel for the many Texans and others suffering the ravaging consequences of February’s winter storms. We now find ourselves facing climate, refugee and migrant crises, along with unresolved racial, religious and political conflicts. I equate this with North America’s jet stream, the regular behavior of which makes for more predictable seasons and rains. According to veterinarian Sarah Hamer at Texas A&M’s College of Veterinary Medicine, both pets developed mild sneezing, and both have recovered.
