I burped while recording, and part of it sounded just like a pig. You might expect this to effect my self esteem, but pigs are actually brutally effective fighters and can hold their breath for several months at a time. True story.
In holland cats are considered to say 'miauw'oscar, the blind cat, has a weird accent though. Especially when he is hungry. . . !. Recorded with a olympus ls-10.
I recorded my toy fox terrier with a zoom h2. The dog was very active and excited about eating, running around, sniffing and making other interesting dog sounds.
