Figure 4. Dual hierarchical dendrogram of metabolites, clustered by pathway, that differed significantly over time in feline fecal samples.

Samples were collected at baseline (days 5–7), at the conclusion of antibiotic administration (days 26–28), and after a 603 day washout (days 631–633) from 16 healthy cats, 8 per group, ⁺ that received 150 mg clindamycin with either a placebo or synbiotic PO once daily for 21 days. ⁺ Feces from one cat (synbiotic group) unavailable on days 631–633.
