In the cat, however, the lens transmits a large portion of the UV light in the range of 320 - 400 nm, while primates transmit virtually no light of these wavelengths. Figure 3 shows the lens transmission spectra of various species. At 50% transmission the second (dotted) line from the left is the cat (50% transmission at ~340 nm), while a primate (squirrel monkey, species representative for humans and other primates) in this graph is line number 7 from the left with (50% transmission at ~410 nm). Hence, cat lenses absorb less light in the UV region, but transmission is virtually nil at 320 nm (Fig. 3). Given that their cones, just like humans, are sensitive to UV, we can reasonably expect that cats can see in the UV region including wavelengths of 320 nm and up. Cats also have the 560 nm (red) cones, like we do, so their maximum wavelength is expectedly similar to ours (~750 nm).

Cefovecin is a new extended-spectrum semisynthetic cephalosporin indicated for the treatment of bacterial infections in dogs and cats. This study evaluated the in vitro activity and spectrum of cefovecin against 2,641 recent clinical isolates (1,660 canine and 981 feline isolates) from Europe and the United States. MIC determinations against cefovecin and other reference antimicrobials were performed by broth microdilution methods recommended by the Clinical and Laboratory Standards Institute (CLSI, formerly NCCLS). Cefovecin demonstrated bactericidal activity against both gram-positive and gram-negative pathogens. Cefovecin exhibited in vitro activity against all major aerobic and anaerobic bacterial pathogens associated with skin, urinary tract, and periodontal infections in dogs and cats. The MIC90 values of cefovecin against Staphylococcus intermedius, Escherichia coli, and Pasteurella multocida were 0.25 μg/ml, 1.0 μg/ml, and 0.06 μg/ml, respectively. No significant differences were observed in terms of the activities of cefovecin against pathogens from different European countries and against pathogens of European and U.S. origin.
